ABSTRACT

Water Oil mill waste is water that still contains some oil, suspended solid, BOD and COD are still relatively high. This study aims to obtain the results of waste water analysis Rotary Biological Contactor (RBC) outlet that meets the standards of PEM. 09 / MENLH / 4/1997 in particular the content of BOD and COD. BOD and COD reduction processes occur in rotating biological contactor (RBC) by Pseudomonas bacteria. In this research used fixed variable flow rate of waste water 7 m3 / hour, rotation speed of RBC 2,12 rpm whereas variable change is urea injection (1,1,1,2 kg / day) and phospat (0,2,0.3,0,4 kg / day) into RBC. RBC outlet water is analyzed daily using API method method 728-53. From the results of the research note that there is a decrease in BOD and COD in waste water after injection of urea and phosphate in RBC. Injections that gave the best results in this study were urea 1.2 kg and phosphate 0.4 kg, for BOD decreased from average 166 ppm to 97 ppm, for COD there was an average decrease of 272 ppm to 198 ppm. Keywords: Rotating Biological Contactor , BOD, COD, Urea, Phospat
