Complete Working Process Of Sewage Treatment Plant

1. Complete Working Process Of Sewage Treatment Plant Sedimentation Decomposition of pollutants It is the initial process that takes place inthe sewage treatment process. At this stage, the water is discharged into the tank for some time. The solid waste then decomposes and settles at the bottom of the tank. This allows the sludge to be scraped off or pumped to another facility for further processing. The tank contains oil and grease as residues and floats on an easily removable surface.

2. The next step after sedimentation is decomposition by exposing the pollutants to oxygen. This is an essential biological process that allows bacteria to break down contaminants. It remains solid and can be divided into two types of systems. Fixed film filtration This uses a combination of filtration to collect what remains in the growth medium. Floating Proliferation System Here sludge and microorganisms mix together to allow waste to be converted to a solid-state. Improve Water Quality By Sand Filtration The third step in the sewage treatment plant is to improve the water quality by sand filtration. A combination of sand filtration techniques achieves this. A unique step in this process is to grow aquatic plants in these bodies of water to remove residual particles and excess phosphorus and nitrogen. Disinfection This is the last step in the home sewage treatment plants. At this stage, many disinfectants are added to the water to remove the remaining microorganisms. This step prepares the water to return to the environment using chlorine light, ozone light, and ultraviolet light.
