Abstract

Water is part of the source of life on the surface of the earth. But often the water used for life contains many organic compounds and other compounds that are harmful to survival. This is due to contamination of water sources by compounds from many places, one of which is waste from the tapioca industry. One way that can be done to reduce water pollution is to reduce the levels of COD and TSS using PAC and aluminum sulfate as coagulant. The ability of PAC and aluminum sulfate as coagulant can be used as coagulant in tapioca wastewater treatment. This study aims to determine the effect of coagulant dose and flocculation time on decreasing COD and TSS levels in tapioca wastewater from Aci Wanakusumah Purbalingga Factory. The method used is coagulation using PAC and aluminum sulfate as a coagulant with a variation of the coagulant dose 2000; 4000; 6000; 8000 and 10,000 mg/L as well as variations in flocculation time 25; 30; 35; 40 and 45 minutes. The results showed that the coagulant dose and flocculation time had an effect on decreasing COD and TSS in tapioca wastewater from Aci Wanakusumah Purbalingga Factory. The best use of PAC coagulant at a dose of 6000 mg/L with a flocculation time of 45 minutes, namely the COD value is 375.2 mg/L and TSS 110 mg/L. While the best use of aluminum sulfate coagulant at a dose of 8000 mg/L with a flocculation time of 45 minutes, namely the COD value is 203.2 mg/L and TSS 590 mg/L.
