Abstract

Produced water contains chemical properties in the form of salt, oil and fat as well as inorganic and organic compounds that can damage the environment if not treated. The purpose of this research is to find out the benefits of using a coagulant from fly ash (Fly Ash) as a produced water treatment with the use of a coagulant from fly ash to improve the water content produced by testing in the form of Oil and grease, turbidity, TSS, water pH. This research is included in the category of experimental methods, and the research stage is literature study. This study used a coagulant from fly ash with the addition of HCL until it was ready to be used as a coagulant. Based on the results of the test using the jar-test method using a coagulant from fly ash, it can reduce some of the tests carried out by oil and grease from 12 mg/L with fly ash concentrations of 4 grams, 6 grams, 8 grams 10 grams, 12 grams and 14 grams down to 11 grams. mg/L, 10 mg/L, 8 mg/L, 7 mg/L, 6 mg/L, <5 mg/L.then turbidity which was initially 16.5 NTU with a decrease to 16.22 NTU; 8.75 NTU; 5.55 NTU; 5.20 NTU; 5 NTU and 3 NTU, then the TSS which was initially 29 mg/L decreased to 23mg/l; 16 mg/L; 14 mg/L; 12 mg/L; 10 mg/L; 8 mg/L, then the Power of hydrogen (pH) which was initially 9.52 dropped to 8; 7.9; 7.7; 7.6; 7.5; 7.3.
