sewage disposal system

There are three main processes in sewage disposal unit: settling tank, pump house, and sprinkler beds. The settling tank used to collect all the waste from main pipe before the process. Pump house used to flow the polluted water so that the water flow in high speed and can be process. And the sprinkler beds as the end of process. First, the waste from house or other building flow through the main sewer and collected in settling tank. The settling tank contents polluted water and also solid things that can not be separated and can be used anymore. In this tank the process is sedimentation so the solid things will separated from the water in the bottom of the tank. The solid things will be burnt or removed from the settling tank, they are removed from the process. After polluted water separated from the solid things, pump house flow the water to the sprinkler beds. In this case there is no process. In the last process, sprinkler beds separate the polluted water from solid things those can’t be processed in settling tank and become sediment. The sprinkler contents brick, chemical filter, jet pump, and rotating arms. The process is: polluted water flow to the jet pump on the rotating arms, the rotating arms rotate the jet pump while it shot the water to the filter. So the process can separates the water from smaller solid things in addition brick and chemical filter process the water become pure water again, separate from chemical contents that dangerous for people. After the process the purified water can be used again or flow the river.

Fire on Top

One of Jakarta’s famous monuments is Monumen Nasional or publicly known as Monas. This 137 centimeters high monument symbolizes the fight of Indonesian people for its independence against the Dutch. The monument is topped with a bronze fire flame statue covered in 35 kilograms of pure gold. It symbolizes the spirit of Indonesian people that never dies. The fire flame is placed on the top terrace. From inside of this terrace we can have the bird-eye view of Jakarta. Monas also has a diorama room inside the base of the monument. The dioramas show the history of Indonesia. Bendera Pusaka, the first Indonesian flag sewed by the first first-lady of Indonesia, is also kept inside the monument along side with the Indonesian independence declaration by the first president and vice president.

Sewage Disposal System

Before sewage from industries is thrown to the river, it needs to be processed to keep the environment safe from chemical or dangerous waste. There are 3 steps until the sewage become a purified water that can enter the river. The first step is done in the settling tank. In this part, the sewage or the polluted waste is run through the main sewer pipe to the settling tank. The polluted water is pumped to the pumped house while the solid sewage that has not decayed is removed and burned in the settling tank. From the pumped house, the remaining waste is pumped to the sprinkler beds. The sprinkler beds consist of brickwork, filter of stones and microorganism, rotating arm, and jets of polluted water. In this step, the polluted water is purified through the filter and rotating arm. After the water is purified, the water can enter the river.

How to Extract Methane Gas from Household Waste

Since technology keeps developing, now there’s a system that is capable of extracting methane gas from household waste. This system is divided into five stages. Firstly, the household waste is put into the warming bed and it will be decayed there. The decayed waste or anaerobe will create methane gas while some of the waste becomes fertilizer. Next, that methane gas goes to the dirt trap. In this stage, the methane gas will be settled so the dirt contained in the gas will be separated. After that, the gas goes to gas indicator. Water in this stage helps the gas to be purified and so methane bubbles can be seen in this stage. Then, the gas goes to the forth stage, which is pressure release. Excess gas occurs when the pressure is high. The last stage of this system is called gas holder. There are inner tubes to hold the methane gas and there are weights above the inner tubes in order to increase the gas pressure. Whenever the gas is needed, the tap can be opened so the methane gas will be released through this tap.

Sewage Disposal Unit



The polluted water that is usually thrown to the river because of the activity of houses and industries can be purified before, so it will reduce the impact of polluted water to the environment. There is a process for purifying the polluted water. First, polluted water is flown to the main server pipe. After that, the main server offers the polluted water into the settling tank. In the settling tank, the undecayed solids in the polluted water is removed and burned. Then, the polluted water that has been separated with the undecayed material goes to the pump house. From the pump house, the water enters the sprinkler beds that have brickwork which can help the process of filtering of stones and micro organisms that are contained by the water and the rotating arms that adjust the jets of polluted water. Finally, the water that has been purified by those processes enters the river and doesn’t pollute its environment.

Description Paragraph about water distribution

The water distribution in every building is different. It could be depend on the design of the house. The water distribution in the diagram below shows in this house there are two system of water distribution. The first is the water distribution for the cold water, and then for the hot water.

First, cold water from the ground is pump, so, it can flows through the mains and then split up into two different ways, to the left and to the top. After that, the mains in the left side distributes the cold water to the sink while the mains in the top side distributes cold water to four different place; toilet, wash basin, bath, and cold water tank. Then, cold water in cold water tank flows to the hot water tank. After cold water being heated in hot water tank, the mains from the hot water tank distributes hot water into two different ways; the mains in the right side distributes hot water to the bath and to the wash basin while the mains in the under side distributes hot water to the sink.

Tahu Sumedang

Tahu is kind of food which basically come from Japan. All kind of tahu was made from soybean curd. But tahu Sumedang is different from just an ordinary tofu. Its crust is brown and really crispy while the inner side is white, soft and very delicious. Tahu Sumedang will be more delicious if it is eaten when still hot. The way to eat tahu Sumedang is also different. Usually tahu Sumedang served with sauce, chili, and lontong (rice steamed in banana leaf). Tahu Sumedang can be a snack in the evening or become a main menu in the lunch and dinner. Tahu Sumedang is also has special package. It packs with the bamboo plait basket and layered with oil paper.

Sewage Disposal Unit

Polluted water from both housing waste and factory waste should be cleaned before its throw away to the river. The process to make the water become purify needs many steps. First, polluted water flows through the main sewer. Then the polluted water enters the settling tank. In the settling tank, water and undecayed solids separated. The undecayed solids will be removed and burned. After that, the water flow to the pump house. After through the pump house, the water flows to the sprinkler beds. In the sprinkler beds water will be filtered from stones and micro organisms and left the jets of polluted water. At last the result of water purification flows to the river.

Methane from Waste

One method of obtaining methane is via biogas generated from waste. At first, the waste goes into a warming bed and gets heated until certain degree in order to separate methane from it. After that, methane is stored into the dirt trap while the waste can be used as fertilizer. Inside the dirt trap, the remain dirt is discarded through the release cap. Next, methane goes into the gas indicator unit to be mixed with water in a sealed container. At a certain temperature and pressure, bubbles are visible. It means some methane in gas form is developed. Then, while the excess gas of high pressure is released to the water inside the pressure release unit, the rest of the gas is stored into inner tubes of the gas holder. Here some weighs are being put on tubes in order to increase gas pressure. Finally, all of the tubes lead to a tap where methane can be released any time.

The Sewage Disposal Units

The waste water need a treatment to remove the sewage contained in it. Sewage is a liquid or semi-liquid wasted that could be very harmful to organism because it contains any toxicate substrate.That’s why the water need to be processed before entering the river.
The processing of water’s sewage involve three stages.First, the water’s sewage will be processed in the settling tank ,then secondly,they will goes to the pump house and the last,the will sent to the sprinkler beds.
The proceeding of sewage begin in the settling tank. The polluted/wasted water sent to the settling tank through the main sewer. After reach the settling tank, the water will be processed by separating the water liquid and the polluting substrate in it (the solid pollutant). The solid pollutants such as the mineral,metal or any other undecayed solids will be removed and burned. And then the water liquid which already separated from it’s solids pollutants sent to the pump house. In the pump house,there is no other procedding happened to the water; the water will be directly pumped to the last stages. The last stages knowned as Sprinkler Beds . The water in this stage will be processed chemically. The water pumped by the pump house goes to the special pipe. This pipe sprinkle the water in to the container below. In the container, the water will be filtered from any toxicate substrate,germs and any harmful microorganicsm using special chemical-filltering method. After the filtering/purified process the clean water will be entering the river thorugh the pipe from the sprinkle beds.

Sewage Disposal Unit

Sewage disposal unit is the way to purified polluted water before enter the river. As we know, this polluted water really dangerous for human health. Before the polluted water purified by sewage disposal unit, the water contents of wastes and dangerous substances from house and factory. Sewage disposal unit help to decrease the dangerous of polluted water before they enter the river.

There are three steps in sewage disposal unit to purify the polluted water. First , the polluted water come from the main sewer and store in the settling tank. In this settling tank, some of substances in polluted water change into sediment formed. Than, the water is pumped by the pump house in oder to make the polluted water enter the sprinkler bed. After that, the polluted water purified in the sprinkle bed. In sprinkler beds, polluted water will be purified and will remove from microorganisms, stones, and other dangerous substances. Water that comes out from sprinkler bed will be safe to enter the river,

Less of dangerous for the environment, and human health.

Three Stages to Remove Contaminants from the Sewage

Sewage is the liquid waste produced by humans which typically contains washing, faeces, urine, laundry waste and other liquid or semi-liquid wastes from household and industry. It is one type of waste water.
In order to discharge the sewage to the environment, there’s needed to be a sewage treatment. Sewage treatment is the process of removing the contaminants from the waste water. Its objective is to produce a waste stream and a solid waste or sludge, which are suitable for discharge and reuse back into environment.
Sewage treatment involves three stages, called primary, secondary, and tertiary treatment. First, in the primary stage, sewage from the main sewer is flowed to the settling tank. In the settling tank, polluted water is separated from its contaminants. These contaminants will be dissolved and become sediment in the bottom of the settling tank. This sediment is an undecayed solids, so it must be removed and burned.
After that, in the secondary stage, the polluted water is distributed to the pump house. In the pump house, polluted water is pump to reach the sprinkler beds, which is located higher than the grounds.
In the tertiary treatment stage, polluted water is filtered in the sprinkler beds. Polluted water, which has reached rotating arms beneath the sprinkler beds, will be sprayed to the sprinkler beds. The sprinkler beds are designed with layer, so the polluted water can be filtered. This filtering process will remove stones and micro-organisms from the polluted water. Water, which has came out from the sprinkler beds, is not polluted and hazardous anymore. Therefore, it can be discharged to the environment.

Water Purification System

Water is needed in many activities in human life such as in household or industrial activities. However, the outcome of these processes will produce polluted water. Before this polluted water is flown into rivers, the water needs to be purified. The purification process is started when the polluted water, along with some other undecayed materials are flown from the main sewer into the settling tank. In this tank, the undecayed materials are removed and burned while the polluted water is pumped by the pump house into the sprinkler beds which function as a filter machine. In this machine, polluted water is flown to rotating arms. In the rotating arms, polluted water is converted into jets which later will flow into the filter side. In the filter sides, stones and microorganism have already arranged properly to filter the polluted material in the water. After passing this process, the outcome purified water will be flown into the rivers.

Three Steps to Remove Sewage from It's Contaminants

Water Distribution in the House

First, the cold water enters the main pipe of the house's water distribution from its source deep in the ground. Then it is distributed to the cold water tank and water taps of bath, wash basin, and toilet in the second floor and also into water tap of sink on the first floor. After it water enters the cold water tank, it goes straight into the hot water tank and changes into hot water. Finally it is distributed to water taps of bath and wash basin on the second floor and water tap of sink on the first floor.

Plaza Senayan

Located next to the newly built STC, Ratu Plaza, and the adjacent Gelora Bung Karno, Plaza Senayan has been well-known among teenagers and people who live in South Jakarta. The 3-storey building with a large atrium in the center routinely accommodates exhibitions such as cars, fashion, computers, and gadgets. The atrium also houses a landmark cuckoo clock, Maryland, that has 6 musical figures that rotates and play hourly. This mall has two rival chain department stores as its anchor tenants lie on the opposite ends of the buildings. Many restaurants and cafes are spread on the second and third level ranging from international to local chains.

Sewage Disposal Unit

Extracting the sewage for entering the river goes through three stages. First, the sewage from main sewer enters the settling tank. On the settling tank, the sewage is settled so it separated into two kinds of form, the liquid one, polluted water, and the solid one, undecayed solids, which is then removed and burned. Second, the polluted water is pumped by the pump house to enter the sprinkler beds. In the sprinkler beds, the rotating arms to be filtered by stones and microorganisms on the brickwork spray the polluted water out. Then, the water is purified and ready to enter the river.

Debus Art

There is a unique art in my hometown, Pandeglang. This art called debus. Debus art is one of the arts that comes from Banten Province, the province where Pandeglang is located. Debus art is an art that really different with other arts. It is not a dance, ceremony or something beautiful to see. Actually debus art is very dangerous. Debus art shows the abilities of its players about their body resistance. Example, in their show, they use knife, sword and other sharp tools then stab those to their part of bodies, like tongue, hand, neck and stomach. Also, they use sulphuric acid and pour it to their bodies. The strange thing is they don’t get injury at all when they do this art. What an ‘art’! . Is it real or is there a mystic thing works on debus art? I don’t know exactly. But the players on debus art are only certain people who have a tough belief to do this dangerous art and before they begin the show, they always do some ritual for their safety.

Water Distribution

In this house, there are two tanks of water, cold water tank and hot water tank. There are also four places that have to be distributed by those tanks of water, bathtub, wash basin, toilet, and sink. First, cold water tank as the main water tank, distributes the cold water into those four places (bathtub, wash basin, toilet, and sink) and also into the hot water tank. In hot water tank, the cold water from cold water tank is changed to be hot water, and then it distributes hot water to three places, bath, wash basin, and sink. So, cold water tank distributes the cold water directly to bathtub, wash basin, toilet, and sink. And the hot water tank gets the water from cold water tank and changes the water to be hot water before distributes to bathtub, wash basin, and sink.

Methan from Household Waste

Methane is a chemical compound that can be extracted from household waste. The process to extract methane starts with mixing the waste with water and stores it into the warming bed. When it reaches a certain temperature, methane will separate it self from the other compound of waste. While the waste can be use as a fertilizer, methane is transferred into the dirt trap. Here, a cap under the methane is open periodically so that the dirt that is still in the methane can be discarded. After the methane is clean of dirt, it is than piped into a Gas Indicator Unit. Here, the methane is mixed with water. When the gas indicator reaches a certain temperature and pressure, methane develops into gas. (The bubbles in water indicate that there is gas). When the gas rises it is then piped into the gas holder. Here the methane is stored for further use. When ever needed the methane can be used by just opening the holder’s tap.

Patin Curry

If you visited Pekanbaru you will find in many restaurants a dish called Patin Curry or in Indonesia called Gulai Ikan Patin. It is a specialty in this city and even in the Province of Riau. The main ingredient of Patin Curry is of course patin fish, coconut milk, curry powder and a little bit of spice. These main ingredients with other ingredients are than boiled until it is thick enough. This dish is very delicious and a unique taste with a mixture of the taste of coconut milk, spice and a little of sour. You really can’t describe the taste of this dish. So whenever you visited Pekanbaru, don’t forget to try it.

Water Distribution

Water distributions in all houses are relatively the same. Water is distributed from the main source into all parts of the house by pipes that are hidden in the floor and the walls of the house. Because of the different location of the facilities that needs water, to fight the gravity pressure, the water is pumped using a special machine. While cold water can directly distribute, warm or hot water can’t. The main source that only contains cold water than send parts of the water into a heater. Here the water is heated to a certain temperature. It is then piped into parts of the house. In every tap where hot water goes trough is a temperature box. This is used to arrange the temperature that comes out of the taps.

Sewage Disposal Unit

Sewage mostly contains potentially dangerous substances which can cause pollution if it is thrown away into the river directly without any purifying process. Sewage can lower the water quality in the river and create a hazard to public health. Therefore, sewage had to be processed in order to make the potentially dangerous substances less dangerous.

The process of purifying sewage is very simple to understand. There are three main places of treatment which hold three main process of purifying sewage, which are the settling tank, the pump house, and the sprinkler beds. In the first step, the sewage enters the settling tank through a main sewer. In the settling tank, after a several while, the undecayed solids will settle in the bottom of the settling tank, for then be removed and burned. The rest of the sewage will be absorbed into the pump house. From the pump house, the sewage will enter the sprinkler beds. There, the filtration process is hold. The sewage from the pump house will be sprayed by the rotation arm into the brick work which contains stones and microorganisms as the filter media. Rocks are one of the recommended media for sewage filtration because it do not fragment or soften on exposure to sewage. Microorganisms, in the other hand, adsorb nutrient from the sewage as food. Finally, after the process of filtration is finish, the purified water can enter the river.

Sewage Disposal Process

Sewage disposal process consists of three steps. They are settling, pumping, and sprinkling. First, the sewage which comes from the main sewer is passed to the settling tank. In the settling tank, the sewage is separated into polluted water and undecayed solids. The undecayed solids will then be removed and burned. After this separation, the polluted water will be pumped to the pump house. Then, the polluted water, which has been pumped, flows to the sprinkler beds which have jets of polluted water that lay on the brick work. The jets of polluted water are pipes which have rotating arms. Moreover, the jets of polluted water filter the polluted water from stones and micro-organism. After the filtration, the water which has been purified is now entering the river.

Extracting Methane Gas

Firstly, waste is put into the warming bed. In this bed, it is separated into 2 parts; the mixture of methane and the fertilizer. The mixture of methane is flowed to the dirt trap. Then it will be separated into methane and dirt, and releases cap. Next, the methane is directed to the gas indicator throughout the sealed top. In this container, it can be noticed as bubbles of methane in water. Afterwards, the methane is continued to the pressure release which has the top open to air. This container contents water and access gas when pressure high. Then, the methane is continued to the gas holder which has inner tubes and weight to increase gas pressure. Finally, after all of the processes have been done, the pure methane is produced and flows throughout the tap.

water circulation

Generally water from the ground is absorbed by the main pipe of the watering system. The main pipe divided to two pipes, pipe to the sink on the first floor and pipe to second floor. On the second floor the pipe divided to two main pipes. Actually the pipe that watering the first and second floor is cold water, so the water in the first main pipe on second floor flow to the cold water tank. This tank is save all the water that absorbed from the ground, this is the first step of watering all the room in the house. Water from the cold water tank divided into two groups. First, flow to the hot water tank, this tank used to boil the water from the cold water tank, and the water from the tank spread to be used in all room in the house. The second group, the water from the cold water tank directly spread to all room without boiled first.

The Process to Producing Methane Gas

Methane gas is extracted from household waste. This waste goes through several stages to producing methane gas. First of all, the waste is thrown into warming bed to be heated with the result that it will produce hot gas. Then, the hot gas rises to the top of warming bed and flows along the pipe that connected to dirt trap. In the dirt trap, the dirt that contained in the gas is precipitated. After the precipitation, the gas flows along the other pipe that ends in the water that put in the vessel with sealed top. In this stage, we can see the methane bubbles flying in the water. Then, the methane rises to the air in the vessel and flows into the pipe. This pipe is divided into two ways. First pipe goes to the inner tubes that equipped with the weight to increase the pressure. As the result, the methane is ready to use by opening the tap. Other pipe is used for excess gas when pressure high. This pipe ends in the water that put in the vessel with its top open to air.

Sewage Disposal Unit

Sewage disposal unit on figure 2 has three stages to purify the polluted water from the sewer. The first stage, called 'Settling Tank', is a place that settled for the polluted water from the main sewer. The polluted water will formed sediment there; so that the polluted water will be separated with the solids content in it. Later on, the undecayed solids will be removed and burned while the polluted water continue the process into the next stages. The second stage is a pump house that just pumping in the polluted water from the settling tank and distribute it into the springkler beds. On this final stage, the polluted water will be directed to the rotating arms. Later, the polluted water will be emitted into the air. Then the rest that falls down will be filtered of stones and microorganisms to yield the purified water that is save to enter the river.

Waste as a national problem

Waste is a public problem, and now even is getting larger to become a nation problem. One of the best solution to this problem is making an efficient waste disposal system. Our disposal system is not bad though, the main problem is could be the people and the community which are irresponsible to the environment.

Waste disposal itself has a complex system until it can be distribute back to the river. Water on river should be clean and hygiene. People obtain water from river for many use. Whenever the water is dirty, it can be dangerous for their health. Government must pay attention for this water usage by providing a waste disposal system before used water reach river. Clean and dirty water are meet at the settling tank. Here, all of the solid waste are removed and burned, the solid waste are usually drown at the bottom. At the end of this settling tank, there is a pipe to flow the water to the pump house. The function of this pump house is to pump the water outside and distribute it to the sprinkler beds. Water is having much of sanitation on this part. Before it reach river, the water must pass through all part of the sanitation system on sprinkler beds, this part is filled with brick and filter of stones and microorganisms.

Water Distribution

Water distribution in our house has to be made in a very simple way and well planned. Principally, water comes from the main pipe, which then distributed into various facilities in and outside the house that need water, through different branches of pipes. Water needs inside the house are sink, bathtub or shower, toilet and washbasin, and outside the house are garden watering and car washing. People who want hot water facility in their house (mostly in the bathroom) will need cold and hot water tank. Cold-water tank is needed for supplying water to the hot water tank to produce hot water. It also could be use as water saving in emergency case when there is no water supply from the main pipe.

Model Essay

Examination not assessment

In the past two decade, the use of formal examinations has become less frequent in many countries. The educational systems in some societies however are still dominated by formal examinations. I believe that, to a certain extent, examinations can give an unfair assessment of a student’s ability. Even thought examination result has been used extensively as a means of assessment in the past, there are times when they do not appear to reflect a student’s ability accurately.

Firstly, examinations can be unfair in several ways. For example, that whole career of a candidate depends upon what he or she does on a certain day and hour of an exam. If the candidate is ill, or if he or she has had some emotional trauma, these factors could have a negative effect on the student’s exam results. Furthermore, some students do not perform well under pressure and require a longer time to reach useful conclusions. Even though they may have studied diligently and know the subject matter thoroughly their performance does not reflect their ability. For these students, examinations appear to be unfair.

Yet, some people believe that examinations make people work hard. They assume that in order to do well, students need to work throughout the course as they know they will have to prove themselves at the end.

However, in many ways, exams have the opposite effect; some candidates merely cram so that they can perform quickly for the demands of the tests. Other forms of assessment such as course work and oral presentations are a more accurate reflection of how hard students work. In the assessment of their ability, students diligence, initiative, deductive reasoning and organizational skills are considered, which are important indicators of ability but are rarely tested in a formal examination.

In conclusion, even though formal examinations have been used in the past, they should no longer be used as the only means of assessment because they can be an unfair indication of the student’s overall ability. In the long term, other less formal means of assessment such as course work or oral presentations are a more useful indicator of the skills required in adult life and, therefore, a more accurate indication of a student’s ability.

extracting methane gas

Extracting methane gas from household waste

Methane gas is one of the residue, or gas that resulted from a chemical process. To extract this gas, we have to through so many processes, first, waste from household is colleted or kept in a place called warming bed. In this container, waste is change into methane, and the rest is released as a benefical composition called fertilizer. Then fertilizer can be used for plant to grow up. Second, the methane from warming bed go to the dirt trap. In this container, methane through a process that makes the methane is separated between the dirt and the methane itself, the dirt then released through a release cap, while the methane continues its journey passes the pipes to the next stop.

The next stop, or the third step is gas indicator, where the methane is dissolved in water and change into methane bubbles. In this place, there is a sealed top in order to keep the methane stay in the tube. The fourth step is pressure release. In this process, methane is extracted into gases. There is excess gas when the pressure high. Methane got certain pressure and temperature, that caused the excess of gas. The last process is Gas Holder. It is in form of inner tube, which has a weight to increase gas pressure, gas from the tube then released through the tap and became “methane gas”. This gas is safety and has less toxic than the waste from household.

Sekaten

SEKATEN

Sekaten is a particular ceremony that held every year to memorize the birth of prophet Muhammad. Sekaten is one of the most precious moment in Yogyakarta, which is held in “Maulud Month”, the month when prophet Muhammad was born. It is usually held on date 5-12 in Maulud Month, the third month in moeslem calendar.At about one month before sekaten ceremony is started, there is a kind of “night park” in the North Alun – alun ( a very large park in Yogyakarta). The most important part in Sekaten is called “Grebeg Maulud”, which is held exactly in the 12^th of Maulud Month.

The festival is started at 7.30 in the morning, begins with the parade of ten troopers from “Keraton”. They bring a thing called “Gunungan”. Gunungan is a group of foods like vegetables, peanuts, red chilli, eggs that arranges in a shape like mountain that represents the whealthy and welfare of Mataram (Kingdom in Yogyakarta). The Gunungan is Brought from North side of Keraton and Kemandungan into “Pagelaran” in North Alun–alun. When the Gunungan and the troopers arrived, they are welcomed with “Tembakan Salvo” and Troopers’ shout,.

Sewage Disposal Unit Saves the Earth’s Water?

Before the wastes can enter the river, they have to be purified first. In order to make them purified, they have to pass some processes that in fact are not really complicated. First, all disposed wastes are flowed through the main sewer to be collected in a tank called settling tank. In this settling tank, the wastes are left to evaporate—in the end there will be two separated materials, undecayed solids and polluted water. The undecayed solids are removed and then burned, while the polluted water is pumped and flows through the pump house to the last place, the sprinkler beds. In the sprinkler beds, the water is entering the first filtrating process, which is rotated by the rotating arms. This will produce some jets of polluted water. These jets of polluted water then will be filtered by stones and microorganism on the brick work. There the water is totally purified and is available to enter the river.

Acehnese Noodles

At the first sight, Acehnese noodles are looked like some ordinary noodles, yet when you look closer, they are not. Acehnese noodles are more slippery than fried noodles, but less than boiled ones.

Water Distribution in House

To tell the truth, water distribution in a house is very simple. First, the water from the mains is pumped, and then it flows through the pipes to all over the house plumbing; the sink, the toilet, the wash basin, the bath, and the water tank. The water which reaches these places is the cold one, therefore, to have some hot water, it needs to flow to the hot water tank first—here the cold water is heated. This water can be saved in the tank for future use or it will flow through the hot water pipe to the bath, the wash basin, and the sink for hot water usage.

How Water Reaches The House

How Water Reaches The House

Water reaches the houses in vary ways. Many years ago, people who lived in rural areas had to get their own water from rivers or from local wells, nowadays, there are more facilities of water supply. In many big cities, there are water-suppy systems to provide water to homes, even in rural areas. This is one of the source of water that we get everyday in our houses. Besides that, the water also come from either a ground-water source, or from a surface-water source such as lake, or reservoir. In common house, there is a separation between cold and hot water that can be used for many purposes.

There is a complicated process of water started from the source until the faucets. First, water from the ground passes the mains to go to the saving water. Second, it goes to cold water tank, which is located in the top of the house, when water collected in cold water tank the water will be processed in certain temperature and pressure to get ideal temperature and cleans the water from bacteria, microorganism and waste. After that, cold water will through the mains and distributed to bath, wash basin, toilet and also sink, because almost every water system in the house needs cold water, the use of cold water is more dominant than the hot water. For hot water process, after it takes to the mains, then it goes to the hot water tank. In this place, water from the ground will be processed, with certain temperature and pressure, after that, hot water is ready to be distributed over the house, such as bath, wash basin and also sink to be used for many purposed.

Clean Water System

The water that we use as a daily need in our house is apparently through a certain simple system. From the underground source, water pumped up to our house by mains. While some water directly distributed into cranes, sinks, toilets, and bath tubs in the house, some collected in a water tank which is put on a high place in a house. The collected water fungtion as a reserve allow the water system takes a rest for taking water from the underground.

Several houses need water as a cold and hot water. The water that straightly distributed into cranes is cold. to get the hot water, water in the tank channeled to the hot water tank and will be processed to distributed as hot water into cranes.
