Types of Water Treatment Processes

Types of Water Treatment Processes

Coagulation or Flocculation

In this process, liquid aluminum sulphate or polymer is added to water.

Dirt particles in the water then stick together or coagulate and continue to stick together until heavy particles are formed.

These heavy dirt particles are called flocs.

The Flocs are then removed from the water by settling or filtration.

FILTRATION

In this process, a filter is designed to remove dirt particles when water flows through it.

Filtration is also a process that is used in disinfection to improve the effectiveness of the disinfection process.

DISINFECTION

Disinfection is a water treatment process that destroys parasites, bacteria and viruses before the water is sent to the distribution system.

Chlorine is an effective disinfectant that is added to water.

Disinfection is an important process that protects against possible biological contamination in the water distribution system.

FLUORIDATION

Water fluoridation is a process where the concentration of the free fluoride ion is adjusted to optimum level sufficiency.

This process helps reduce decay that is caused by the excess fluoride in the water.

pH Correction

This process adjusts the pH levels in the water by adding lime to stabilize natural soft water. pH correction prevents corrosion in the distribution system and water pipes.
