The Processes of Sewage Disposal

Sewage is needed to be disposed and purified. These processes are quite complicated. There are three main processes; they are the settling process, the pumping process, and the filtering process. Sewages from houses and factories pass by sewers and reach main sewer. And then, the sewage is separated into polluted water and undecayed solids. These solids will be removed and burned. After that, the polluted water is pumped in pump house. This pumping is meant to channels polluted water to the sprinkler beds. In sprinkler beds, purification of polluted water is occurred. The polluted water is pumped to the top of sprinkler beds and passes by rotating arms that produces jets of polluted water. The jets infiltrate through layers that set up between brick work. This process makes the polluted water is filtered and purified from stones and microorganisms. After that, the purified water is flowed into river.
