Explanation:
Drinking Water Treatment
Sedimentation
The heavy particles (floc) settle to the bottom and the clear water moves to filtration.
Storage
Water is placed in a closed tank or reservoir for disinfection to take place. The water then flows through pipes to homes and businesses in the community.
Flocculation

Coagulation
Filtration
The water passes through filters, some made of layers of sand, gravel, and charcoal that help remove even smaller particles.
Disinfection
A small amount of chlorine is added or some other disinfection method is used to kill any bacteria or microorganisms that may be in the water.
Coagulation removes dirt and other particles suspended in water. Alum and other chemicals are added to water to form tiny sticky particles called “floc” which attract the dirt particles. The combined weight of the dirt and the alum (floc) become heavy enough to sink to the bottom during sedimentation.
