Sewage treatment plants play an essential role in society. This is an aspect that is often misunderstood and neglected by people because people do not understand it at all. However, sewage treatment plants do a lot of important work.
Sewage treatment plants are also called domestic waste treatment plants. Sewage treatment plants will have to clean and treat sewage coming from the process house and commercial purposes.
Sewage treatment plants generally do not include wastes that come from heavy pollutant sources such as industrial plants that release large doses of chemical waste products.
In the design and construction of modern sewage plants, it is basically made up of three phases: primary stage, secondary phase, and tertiary phase. In the primary phase, simple materials are taken out of the wastewater to be eliminated.
Floating solids such as oil, grease, and fat are skimmed and also taken out of the surface area. At the secondary level, the main goal would be to remove organic contaminants in the wastewater.
In the secondary phase, the largest technical treatment and removal of waste is about to take place. There are many ways to reduce and eliminate organic pollution in wastewater.
In tertiary treatment, where the final treatment will take place, the main objective is to make the water as clean as it can be before discharging it into the natural environment. This is accomplished by man-made or artificial systems of filtration.
