Sewage Disposal Unit

A sewage disposal unit doesn’t work in a complicated way. First, sewage from main sewer is flown to settling tank through the main sewer. In the settling tank, the sewage is separated into two forms, the solid forms which called the undecayed solids waste and the liquid forms which called polluted water. The undecayed solids waste, which stays in the bottom of the tank, are removed from the settling tank and burnt outside, while the polluted water is distributed to the pump house. The polluted water is pumped from the pump house to the sprinkler beds, where the purifying water process is taken. At the top of sprinkler bed there are rotating arms which can sprinkle the polluted water into sprinkler bed. The speed of the rotating arm makes the polluted water that flows through become a jet. Then, the jet of polluted water is sprayed of the rotating arms to the brick work. The stones and micro-organisms are filtered in this process. After going through that final process, the purified water is distributed back to enter the river.

Thank you

Dear All,
Thank you so much for working together this semester. I really have great time in class, and also I really enjoy reading all of your essay. Please keep in touch in the future. You all have my contact. Good luck with your study.

TASK 4 SEWAGE WATER DISPOSAL

Technology about water purification was discovered by the human hundreds years ago. One example of water purification technology is sewage disposal unit. Sewage disposal unit is consist of three main parts : settling tank, pump house, and sprinkler beds.In the first of purifying process with sewage disposal unit, sewage is flown to the settling tank from main sewer . In the settling tank, sewage component will be separated in two form. The solid form called undecayed solids will move into the base of settling tank and then will be burned and removed. Next the liquid component called polluted water will be flown into pump house. In the pump house, polluted water will be pumped into sprinkler beds. In the splinker beds polluted water moves to the rotary arm which can directs the polluted water to the filtering zone. In the filtering zone, polluted water will be filtered from microorganism and stones. The result of this filtering process is purified water and will be flown into the river.
