Sewage Disposal Mechanism

Sewage from factory which contains dangerous materials needs some treatment before flown into the river safely. The method to treat the sewage is Sewage Disposal Mechanism. First of all, the sewage will be flown to the main sewer. From the main sewer, the sewage will be flown to the settling tank where the sewage will be separated in two forms. Solid matter which is sediment at the bottom will be removed and burned. Through the pump house, the liquid sewage which means polluted water from the settling tank is flowed to the sprinkler bed. In this bed, water is pumped by the hydraulic and water will reach the surface of the sprinkler bed. Then, water will be rotated by the rotating arm. The polluted water is filtered by contacting stones and microorganism with the water. Finally, this clean water can be flown to the river.
