Abstract

Abstract
Research about treatment of waste water power plant operation of PT Indonesia Power at
Denpasar with the flotation and activated sludge method has been carried out. The objective
of research is determine optimum treatment time in flotation and activated sludge to
decrease oil and COD content of wastewater. In the flotation stage, 8 liters of waste water
power plant operation of PT Indonesia Power aerated by aerators for 60 minutes. After the
flotation treatment waste water treated by activated sludge method for 24 hours. The
results of research showed that the time of treatment in the 60th minute the flotation process
capable to reduce the oil contents reach 450 mg/L with the treatment effectiveness of 97,92%.
At the time of treatment in the 24 hours, the activated sludge process has been able to
reduce the oil content reach 0 mg/L with treatment effectiveness is 100% and reduce COD
value reach 27,63 mg/L with the treatment effectiveness of 70,59%. Oil content and COD
value obtained from are effluent of flotation and activated sludge below Class III Water
Quality according to PerGub Bali Number 8 in 2007 (1 mg/L and 50 mg/L respectively).
