How does a sewage treatment plant work?
the sewage plant works by having a primary treatment that help take out all of the excess oil and trash that goes into it then comes the secondary treatment that they put chloride in it to kill all the bacteria or anotherway putting it into an o zone layer which acts like a dienfactant torwards bacteria andlast it mightbe transffered to the river, lake, or stream and afterthat it goes to your homes!
Overview of Sewage Treatment Plant Operation of a sewage treatment plant generally works the same no matter your location in the U.S. Removing total suspended solids (TSS) and biochemical oxygen demanding waste (BOD) are the main goals of a sewage treatment plant. Extracting these pollutants reduces the chance of fish kill due to eutrophication and disease carrying microorganisms forming on the suspended solids. Eutrophication is basically the decreasing of oxygen to levels unfit for life. U.S. federal law requires wastewater treatment to be completed. Preliminary and Primary Sewage Treatment Once wastewater arrives at the sewage treatment plant, preliminary treatment begins with wastewater flowing through large bar screens that removes big objects and particles such as sand and gravel. Wastewater then runs through the comminutor that shreds organic matter such as paper. This readies the wastewater for primary treatment. After flowing to settling tanks, oily materials float to the surf
