ABOUT DRINKING WATER FILTRATION

 

Water treatment filtration involves the removal of suspended particles from water by passing the water through a filtration medium. As the water passes through the filter, floc, minerals, microorganisms and other impurities get stuck in the filter and are removed from the filtered water. Passage can be blocked by physical obstruction, biological action, adsorption, absorption or a combination of ways. Filtration is usually the final step in the solids removal process during water treatment which typically begins with coagulation and advances through flocculation and sedimentation.  

Unfiltered or turbid water is difficult to disinfect because microorganisms growing on suspended particles are often harder to kill than when they are separated from the particles. Turbidity can also cause unwanted taste and odor issues in the potable water supply. Drinking water filtration is also used to remove microorganisms that are resistant to traditional methods of disinfection such as chlorination. By requiring a low turbidity in finished water, water treatment plants are ensuring that few or no microorganisms such as Giardia are present in finished drinking water.

There are three typical methods of clean water filtration used during the water treatment process. Conventional filtration follows coagulation, flocculation and sedimentation and precedes disinfection. Direct Filtration follows coagulation and flocculation when there is no sedimentation step. The final method called In-Line Filtration takes place without flocculation or sedimentation. A coagulant chemical is added to the water just before filtration and coagulation occurs in the filter. 

 There are many types of filter media being used in today’s water treatment industry.
