Community Water Treatment

Coagulation and flocculation - Coagulation and flocculation are two separate processes, used in succession, to overcome the forces stabilising the suspended particles. While coagulation neutralises the charges on the particles, flocculation enables them to bind together, making them bigger, so that they can be more easily separated from the liquid.

Sedimentation - Sedimentation is a common way of treating water. It is a process that removes solids that float and settle in the water. The process relies on the use of sedimentation tanks that remove larger solids. Subsequent treatment processes may be used after sedimentation.

Filtration - Using filtration in water treatment, solid particles are entirely removed from the water. This can be from groundwater, surface water or even pre-treated wastewater. These processes in water treatment have a clear objective: to provide the correct quality of water for the specific industrial application.

Disinfection - Disinfection is a physical or chemical process in which pathogenic microorganisms are deactivated or killed. Examples of chemical disinfectants are chlorine, chlorine dioxide, and ozone
