Sewage Disposal Unit

Dangerous liquid sewage from the industry can be processed through purification process in the sewage disposal unit. Generally, the sewage will flowed into three main parts of the sewage disposal unit. First, the sewage from the main sewer flowed into the settling tank. In the settling tank, the undecayed solids from the sewage will stay in the tank base. Then, it’s removed and burned. Then, polluted water from the settling tank is flowed into the pump house. Then the polluted water is pumped from the pump house to the sprinkler bed. In the sprinkler bed, the polluted water is flowed to the rotating arms. Then, the polluted water is sprayed rotationally to the top surface of sprinkler bed. Then, it’s purified by the filter which contain stones and micro-organism. Finally, the purified water is safe to be flowed into the river.
