What are the different methods of waste water treatment?

There are several different methods of wastewater treatment, including physical, chemical, and biological processes. Physical processes involve the removal of larger particles through methods such as screening and sedimentation. Chemical processes use chemicals to neutralize contaminants and remove pollutants from the water. Biological processes utilize microorganisms to break down organic matter and remove harmful substances from the water. Combination methods may also be used, such as the popular activated sludge process which combines biological treatment with aeration and settling tanks. Each method has its own advantages and may be used depending on the specific needs and requirements of the wastewater being treated.
