SUMMARY Maredan clay contained Al2O3 and Fe2O3 of 28.186% and 6.452% used as a precursor for liquid coagulant synthesis. Liquid coagulant was obtained by calcining clay at 700oC for 1 hour and leaching with 0.2 mol H2SO4 100oC for 2 hours. Coagulants were characterized to determine the cation of Al3+ , Fe3+ and pH. Liquid coagulant were tested to reduce some of the Siak River water parame…
