What are the main unit processes involved in water treatment?

Question

Accepted Answer

Main unit processes in water treatment include coagulation, flocculation, sedimentation, filtration, and disinfection.

Coagulation: Chemicals are added to water to destabilize particles and allow them to clump together.
Flocculation: Gentle mixing to encourage the particles to form larger flocs.
Sedimentation: Flocs settle to the bottom of a tank due to gravity.
Filtration: Water passes through filters to remove remaining particles.
Disinfection: Chemicals like chlorine or UV light are used to kill any remaining bacteria and pathogens.
