What is the best technique for treatment of wastewater?
Chemical. Chlorine is the chemical most often used in treating sewage and other types of wastewater. The process is called chlorination. This is the most effective means of destroying a variety of viruses and bacteria.
What is waste treatment process?

What are the different water treatment processes methods?
— boiling; — household slow sand filter; — domestic chlorination. — storage and sedimentation; — up-flow roughing filter; — slow sand filtration; — chlorination in piped water-supply systems. through a piece of fine, clean, cotton cloth to remove some of the suspended solids.
What are the water treatment methods?
Top 7 Methods of Water Treatment
- Coagulation / Flocculation. Coagulation is adding liquid aluminum sulfate or alum and/or polymer to raw or untreated water.
- Sedimentation. When water and flocs undergo the treatment process, they go into sedimentation basins.
- Filtration.
- Disinfection.
- Sludge Drying.
- Fluoridation.
- pH Correction.
What is SBR in wastewater treatment plant?
The sequencing batch reactor (SBR) is a fill-and- draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single “batch” reactor, treated to remove undesirable components, and then discharged.
