Sewage Disposal Unit

A sewage disposal unit doesn’t work in a complicated way. First, waste mostly comes from houses flows through the main sewer to the settling tank. In the settling tank, the waste is separated into two forms, the undecayed solids waste and the polluted water. The undecayed solids waste are removed from the settling tank and burnt outside, while the polluted water is distributed to the pump house. The second process is taken in the pump house. The polluted water is pumped from the pump house to the sprinkler beds, where the purifying water process is taken. Next, the polluted water is pumped out to the rotating arms which have jets to rotate them. The polluted water is sprayed out of the rotating arms to the brick work. The brick work is a part of the sprinkler beds which has a function to filter the polluted water from stones and micro-organisms. After the water is filtered, the purified water is distributed to river.
