Process of
Water Treatment Plants
SCREENING – This step removes any large debris
Disinfection – this step is used to kill the organisms in
the water that may cause diseases for humans (pathogens).
COAGULATION – Aluminum SULFATE is added to the water
entering that plant.
The reaction of the chemically treated water to the mixing
causes the small; light-weight particles to clump together
(coagulate) into much larger particles.
FLOCCULATION - the larger particles continue to combine
(flocculate) into much larger and heavier particles and
begin to sink (settle).
SEDIMENTATION - in this step the water enters several large
tanks so that the large, heavy particles settle in to the
bottom.
FILTRATION The water is filtered through a thick bed of
sand.
Disinfection – this step is used to kill the organisms in
the water that may cause diseases for humans (pathogens).
