Sewage Treatment Plant Process

Sewage treatment is the process of removing contaminants from wastewater before it is discharged back into the environment. It involves several key steps.

First Step:

Physical processes like screening and sedimentation remove large solid materials and settleable particles.

Second Step:

Biological processes utilise microorganisms to break down organic matter, converting it into harmless byproducts. This is often followed by secondary treatment, where the remaining organic and nutrient pollutants are further reduced.

Third Step:

Tertiary treatment may be employed to remove specific contaminants, such as phosphorus or pathogens, ensuring the treated water meets environmental standards before being released. Sewage treatment plays a crucial role in safeguarding public health and preserving the quality of water bodies.
