The problem of pollution of the aquatic environment caused by the disposal of industrial liquid waste can be prevented by controlling the waste treatment. Bulking is a common problem in the secondary processing of mixed liquor. Many studies have been conducted to address this problem. This study aims to produce an efficient composition to overcome bulking due to low DO in industrial organic wastewater by using a combination system of the biofilter and RAS (return active sludge). The research method used is a laboratory experiment. The tests carried out were the variation of aeration time (A), the addition of a 1 cm diameter biofilter (B), and the variation of the addition of RAS (C), using RAL. Further test using Duncan`s test. The results showed that the combined biofilter and RAS system resulted in time effectiveness of 2 hours on the variation of the biofilter 200 and RAS as much as 10% in dealing with bulking. The results of the Duncan test showed that there was a very significant difference between treatments in dealing with bulking.
