Performance intensification of the coagulation process in drinking water treatment

Surface water pollution has increased, owing to industrial development and population growth. Consequently, it is important find alternative drinking treatment strategies, which cater for changes in the quality of raw water. This study compared efficiency different coagulants treating that feeds a plant (WTP). Using jar testing equipment number physicochemical parameters, an investigation was conducted establish optimum conditions aluminium chloride (A), ferric (B), chitosan (C), their performance with sulphate (D), coagulant used at WTP. The turbidity removal efficiencies single were order: B (95.7%) > A (94.7%) C (94.4%), doses 60, 50, 0.6 mg/L, respectively. achieved high turbidity, total dissolved solids (TDS), ultraviolet absorbance 254 nm (UV254) conductivity under acidic conditions. For dual coagulants, there gradual increase tested parameters increasing pH. Combined more effective highest being exhibited by A/C combination. Overall, proved be suitable alternatives D, since they had comparable performances.
