The removal of contaminants present in coal wastewater is a physical process that does not have a major impact on chemical and biological characteristics. Previous research recommended the treatment process using the electrocoagulation method because of its high contaminant removal success compared to other treatment technologies. This study aims to determine the effect of flow during the electrocoagulation process in the removal of Total Suspended Solid (TSS) and compared using variations in current strength and hydraulic retention time. The reactor configuration used is a continuous electrocoagulation reactor configuration and uses 12 aluminum electrodes as anodes and cathodes. The variation used in this study is the variation of hydraulic retention time of 15 minutes; 30 minutes; 45 minutes in a continuous electrocoagulation reactor with a capacity of 15 L, so that the flow rate obtained is 1 L/minute; 0.5 L/minute; 0.3 L/minute with a current strength variation of 2 Ampere; 4 Ampere; 6 Ampere. The results showed that the electrocoagulation process can remove TSS levels. The 1 L/min variation with a current strength of 2 Amperes is able to remove TSS by 96.43% with an initial concentration of 1260.1 mg/L to 45 mg/L, these levels have met the quality standards of the East Kalimantan Provincial Regulation Number 02 of 2011 concerning Water Quality Management and Water Pollution Control, but further study is still needed regarding further processing related to sludge formed during the electrocoagulation process.
