How Does Wastewater Treatment Work?

After the sewage leaves the settling tank in the primary stage, it is pumped into an aeration tank, where it is mixed with air and sludge loaded with bacteria and allowed to remain for several hours. During this time, the bacteria break down the organic matter into harmless by-products.

How Does Wastewater Treatment Work?

Wastewater treatment is a process used to convert wastewater into an effluent that can be returned to the environment with minimal environmental impact.

]The process involves removing pollutants and other contaminants from the water before it is released back into the environment.

Wastewater treatment processes are designed to remove suspended solids and other contaminants, such as nutrients, metals, and microorganisms, from wastewater.

The wastewater treatment process begins with the physical separation of solids and oils from the wastewater. This is done by passing the wastewater through screens or filters, which remove large particles of solid matter.

The remaining wastewater is then passed through a settling tank, where heavier solids settle out of the water. The liquid that remains is called primary effluent.

The primary effluent is then passed through a series of tanks, such as aeration tanks, where oxygen is added to the water.

This process helps to break down organic matter and reduce the levels of bacteria and other microorganisms. The water is then passed through secondary settling tanks, where more solid matter settles out of the water.

At this point, the secondary effluent may be passed through additional tanks to remove phosphorus and nitrogen, which are pollutants that can cause algal blooms and other environmental damage if released into the environment.
