Untreated drinking water is treated via a series of purification actions. As the untreated drinking water enters the treatment flower, chemicals such as chlorine and ammonia tend to be added to the water. Semi-annually, carbon may be put into assist in the effects of taste and smell. Coagulation and flocculation are the processes that remove turbidity or even color from the drinking water with the use of chemical coagulants, ferric sulfate as well as polymer. Lime is actually added to correct the actual pH of the drinking water and particles within the water begin to contact form a floc which settles to the bottom part of the clarifier container and is removed. larified water is divided from fine sediments in the water through filters that eliminate any remaining revoked particles in the drinking water.
