The production of batik generates a large volume of wastewater with complex nature and characteristics such as high temperature, pH, BOD, COD, and TSS. In Jababeka Industrial Estate, Wastewater from batik industries is treated by going through a facultative equalization tank before going to the next treatment units. Hypothetically, by optimizing the facultative equalization tank, it will improve the effluent quality and increase COD and Ammonia’s removal efficiency. This research used 4 microbial products that are commercially available and can be applied easily in real-life operating conditions. The study aimed to determine the effect of bacteria addition and its removal efficiency for batik wastewater effluent from batik industries in Jababeka Industrial Estate. the parameters measured were pH, concentration of COD and ammonia. The addition of bacteria reduced COD and Ammonia concentration in the wastewater and changed the wastewater’s pH and color. The result indicates that for high COD and ammonia loads, the M-Aerobic bacteria is the best type of bacteria with a removal efficiency of 63.39% and 99%, respectively. However, ANOVA analysis indicates that there is no statistically significant difference between the treatment groups. It is recommended for this experiment to be repeated in a continuous reactor.
