Wastewater treatment removes contaminants from used water so it can be safely returned to the environment or reused.
It is essential for public health and environmental protection.
Treatment proceeds in stages: primary treatment removes solids by settling; secondary treatment uses biological processes like activated sludge to break down organic matter; and tertiary treatment removes remaining nutrients and pathogens using filtration, disinfection or advanced oxidation.
Modern technologies such as membrane bioreactors and advanced oxidation processes enable high-quality reuse of treated water.
