Application of Coagulation-advanced Oxidation Process by O3/GAC in the Fan Belt Wastewater Treatment

The aim of the research is to obtain fan belt wastewater treatment results in accordance with quality standards of that have been set by the government. The initial quality of the fan belt industry waste water was 1950 mg/liter of total suspended solid (TSS), 9950 mg/liter of chemical oxygen demand (COD), the dark purple colored and smelled. The experimental variables are the type of coagulants (Alum and Poly Ammonium Chloride), the initial pH of the coagulation process (5.0;7.0 and 9.0) and the process sequence was coagulation-advanced oxidation process (C-AOP) as well as advanced oxidation-coagulation (AOP-C). The optimal result of this research obtained for process sequence of the C-AOP with of Poly ammonium chloride as coagulant at pH 9.0. It can remove COD and TSS respectively by 96% and 99%, reduction color as well as odor significantly.
