This research is aimed to reduce the turbidity, organic substances and color of peat water using liquid coagulant based derived natural clays. The liquid coagulants were synthesized by two steps processes which are calcination of natural clays on 700oC for 1 hour, and followed by extraction of calcined clays using a solution of 0.6 moles sulphuric acid at 80oC (KLC80) and 100oC (KLC100) for 2 hours, respectively. The liquid coagulants then characterized cations content using AAS method and pH. Afterward the liquid coagulants were used in a two stages coagulation process having coagulant-peat water rasio of 150, 120 and 110 (V/V) respectively. It has found of both coagulants have a very acidic pH with nearly equal content of Al3+ and Fe3+. Investigation of two stages coagulation treatments of peat water using liquid coagulant has given a satisfactory finding on 1 10 (V/V) rasio. As a result KLC80 has proved on reducing peat water turbidity 89.5 %, organic substances 22.5 % and 49.5 % color, respectively, which there were higher than KLC100 does. The turbidity of post-coagulation process of peat water by KLC80 and KLC100 coagulants have fulfilled PERMENKES No.416/ MENKES/ PER/IV/1990 on Water Quality Requirements and Supervision with values of 1.21 and 1.42 NTU.
