DESALINATION REJECT WATER UTILIZATION for REVERSE OSMOSIS PLANT RAW WATER

Desalination plant serves to treat seawater into raw water through the evaporation process. In Muara Tawar power plant, desalination plant commonly used to supply raw water for combined cycle power plant. Distillate water from desalination plant must have certain criteria (conductivity <20 µs/cm). Distillate water with conductivity higher than 20 µs/cm will be removed. Reverse osmosis (RO) plant in block 5 in Muara Tawar power plant need raw water with conductivity <32000 µs/cm so that dump water from block 1 can be utilized. Desalination dump water can be utilized as a raw water for RO plant block 5. By utilizing dump water from block 1 to raw water block 5 there are several financial benefits. Until December 2017 saving by using dump water is IDR 586,587,603, - and saving from electricity is IDR 4,069,531, -.
