(FeCl 3 ) () : Comparison of the Performance of Poly Aluminum Chloride (), Ferric Chloride (FeCl 3 ), in Turbidity and Organic Matter Removal; from Water Source, Case-Study: Karaj River, in Tehran Water Treatment Plant No. 2 Mohammad Abdolah zadeh Ali Torabian 2 Amir Hesam Hassani 3 (Received June, 28 Accepted Jan. 3, 29) Abstract Coagulation and flocculation are the principal units in water treatment processes. In this study, the Jar test was used to investigate the effects of the ph and on FeCl 3 and coagulants for further removal of turbidity, organic matter, aluminum, total organic carbon (), dissolved organic carbon (DOC), organic Aadsorption at a wavelength of 254 nm (UV 254 nm ), alkalinity, residual aluminum and ferric, total trihalomethans (TTHMs) in the Karaj River in the year These experiments were conducted through a bench scale study using conventional coagulation in the influent to Tehran Water Treatment Plant No. 2 (TWTP2).With normal ph levels, demonstrated more efficiency than FeCl 3 in removing turbidity,, UV 254 nm, and TTHMs. The lower coagulant consumption, high floc size, lower floc detention time, lower sludge production, lack of the need for ph adjustment in turbidity of 25 and the lower alum consumption were the advantages of application instead of FeCl 3 as a coagulant. Also, application was efficient at low turbidity (2 ), average turbidity (6 ), and high turbidity ( ) in, turbidity, UV254 nm, and DOC removal. Thus, is an economical alternative as a coagulant in TWTP2. Keywords: Poly Aluminum Chloride (), Ferric Chloride (FeCl 3 ), Conventional Coagulation and Flocculation..
