explain how waste water is treated in the different stage of a waste water treatment plant
Answers
Answer:
first wastewater is filter
then it is left to store in Big tank to to occur the process of sedimentation
after the impurities are sedimented down then the water is send to again for filtration
after that water is chlorinated
Answer:
The sewage treatment consists of three processes:
1) Primary treatment: In this process, the effluent or the sewage flows through huge tanks called the primary sedimentation tanks.
In these tanks, the sludge settles down while grease and oil float on the surface and are removed.
These tanks have scrapers that continuously push the sludge that is collected, towards the hopper in the base of the tank
2) Secondary treatment: In this process, the biological waste from human waste, soap, food waste, and detergent are substantially degraded.
Most of the municipal sewage water treatment plants treat the sewage that is settled through the aerobic process.
The effluent after the primary treatment has dissolved biological matter is then converted into clean water by making use of the bacterial and waterborne aerobic micro-organisms that absorb the pollutants.
The effluents from this process are clean enough to be discharged into the rivers.
3) Tertiary treatment: This is the final stage of filtration where the effluent is treated further to its best quality before being discharged to the environment.
The tertiary treatment has to ensure very high standards of treating the effluents to be cleaner than the stream or river water.
It reduces the phosphorous and ammoniacal nitrogen.
