Wastewater Treatment

Wastewater treatment is the process of removing contaminants from wastewater to produce water that is safe for discharge into the environment or for reuse. It typically involves multiple stages, including preliminary treatment (removal of large debris), primary treatment (sedimentation of solid waste), secondary treatment (biological processes to break down organic matter), and sometimes tertiary treatment (advanced filtration or chemical treatments). The goal is to reduce pollutants and improve water quality before discharge or reuse.

Tertiary Treatment of Wastewater: Achieving Advanced Purification

by
An advanced filtration system in a wastewater plant, with processes like chlorination and UV disinfection.

Tertiary treatment of wastewater is a process that removes the remaining contaminants in the wastewater that have not been removed by primary and secondary treatment. Tertiary treatment is the final stage of treatment in wastewater treatment plants (WWTPs), and it is essential to remove the remaining pollutants from the wastewater before it is discharged into … Read more

Preliminary Treatment of Wastewater
