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.

I have a blog containing good information on global warming. Ozone has doubled since the mid-19th century due to chemical emissions from vehicles, industrial processes and the burning of forests, the British climate researchers wrote. Carbon dioxide has also risen over that period. History of global warming is very deep since 1850.
