Water Quality Assessment and Comparative Study of Coagulants and Flocculants with Different Dosages –A Review

Water resources are equally important for natural ecosystem and human development. Rapid industrialization and indiscriminate use of chemical fertilizers and pesticides in agriculture are causing deterioration of water quality by varied pollution in aquatic biota. Due to use of contaminated water, human population suffers from water borne diseases. It is therefore essential to assist the quality of water at regular intervals of time. Parameters that may be tested include temperature, pH, and turbidity, hardness. The present review paper describes about the comparative study of water quality by using different dosages of coagulants and flocculants like Alum, Poly Aluminum chloride (PAC), Poly Electrolyte (PE) and combination of PAC+PE.
