Turbidity Removal efficiency of different inorganic coagulants during water treatment - A review

NIZEYIMANA Ladislas

Abstract


Accessible drinking water sources, including ground and surface waters, are being polluted because of changing climates and other human activities. Turbidity is a critical factor in water treatment processes because it significantly impacts water quality, as it is a measure of the transparency of water, with turbidity increasing as the concentration of suspended particulates increases. This process removes turbidity from the surface water and converts dissolved organic matter into suspended colloidal material. Conventional iron and aluminum salts and synthetic polymers are commonly used as chemical coagulants for surface water treatment. Coagulation-flocculation is also the most conventional treatment process in water treatment plants.

The turbidity removal for Alum varies from 94.14% to 99%. The turbidity removal for PACl ranges from 88% to 99% and 77% to 99% for Ferric chloride coagulant. The alum and ferric chloride are among the most extensively used chemical coagulants in many countries.
