ABOUT DRINKING WATER DISINFECTION

WATER DISINFECTION

Water disinfection is the process of removing unwanted chemicals, biological contaminants, suspended solids and gases from contaminated water. It is also the elimination, deactivation or killing of pathogenic microorganisms.

Methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or activated sludge, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

Ozonators produce small quantities of ozone which is a strong oxidizing agent that kills pathogens over a short period of time.
