Produce water is an effluent dicharge from oil processing, which have an physical-chemical characteristic is a high organic pollutan as an Chemical Oxygen Demand (COD), ammonium, sulfida, phenol, oil content and high tempertur. Sometimes the pollutan also metal content as a mercury which an toxic substance that can be an inhibitor for biological processing.Fivestrain microorganisms i.e :Pseudomonassp, Staphylococcusaureus, Thiobacillusferrooxidans, Bacillus sp, and Alcaligenesto be aclimated using produce water as a carbon source from real waste on batch system for 30 days. The condition in the batch system is a biomass concentration 10% (v/v), waste concentration 100%, CNP ratio 100:10:1, incubation time 4 days at room temperature (280C). Growth rate microorganism was checked for make sure that microorganism could be growth, and the kinetic constanta obtained is specific growth rate (?) : 0,037/h, maximum growth rate (?max): 0.45/dayorganic removal coefficient (k) : 207.8 mg/l COD/day, and half velocity constant (Ks) : 35 mg COD/l. The operation continued to the biological reactor with step aeration processing after batch system. The flow rate in to continues reactor is0,90 l/h with detention time 2 (two) days and return sludge (r) : 0.5, dissolved oxygen > 2 mg/l and sampling periodic interval 0, 2 and 4 days.The result show that removal efficiency for organic matter as a COD is 87.1%, ammonia 95.88 %, sulfide 99.2% and phenol 99.7%
