  • Abstract:
  • This paper describes the testing, implementation and interim results of a full-scale coagulant changeover from Aluminum Sulfate (Alum) to Poly Aluminum Chloride (PAC) at a large conventional water treatment plant in thermal power plant. Research was conducted at The Koradi Thermal Power Plant last year to determine if a coagulant other than Alum would work better. Two inorganic coagulating agents, alum, & polyaluminum chloride (PAC) were used to clarify samples; samples of raw water collected from Pench river, seasonwise, of different turbidity. Jar testing and pilot plant work conducted determined that the 18% Al2O3 non-sulfated and PAC would perform quite well. A one year full-scale PAC trial, using existing infrastructure was initiated in August-2014. Water quality and operational data was used to determine the effectiveness of the PAC over the different seasons.
