The wastewater enters an aeration tank, where it is mixed with sludge. Air is then pumped into the aeration tank to facilitate the growth of bacteria and other small organisms within the sludge. The bacteria and other microorganisms break down the organic matter in the water into harmless byproducts.
How Sewage Treatment Plant Works?
Sewage treatment plant plays a very important role in the environment as it helps in eliminating pollutants from wastewater.
This process of removing contaminants from wastewater is known as sewage treatment. The process of sewage treatment involves a series of steps that are aimed at removing and reducing the pollutants present in the wastewater so that it can be safely discharged into the environment.
The first step in the process of sewage treatment is to collect the wastewater from homes, businesses and other sources.
The wastewater is then transported to the sewage treatment plant where it is separated into solids and liquids. The solids are then treated and separated into two categories, namely, primary and secondary solids.
Primary solids are those that can be removed through screening, settling or sedimentation. Secondary solids are those that require further treatment before being discharged into the environment.
Once the solids have been separated, the liquid phase of the wastewater is then directed to the aeration tank. In this tank, oxygen is added to the wastewater in order to facilitate the growth of bacteria and other microorganisms.
These microorganisms consume the organic matter present in the wastewater, thus breaking it down into simpler compounds. The presence of oxygen also helps in the oxidation process, which further breaks down the organic matter.
