    Abstract

    Domestic wastewater is waste dominant contaminate besides industrial disposal. Domestic wastewater produce organic compound that can be low water quality. Besides, domestic wastewater contains high total solid causing turbidity and decrease penetration of sunlight for organism photosynthetic. So that needs processing that can be removed by reactor Rotary Biological Contactor (RBC) for standard environment. RBC a reactor that consists of several discs rotates with certain rotation speed. At the discs rotate, part of the discs removes the organic material from wastewater. At the discs contact with the air biomass adsorbs oxygen so that reached aerobic condition. As factor condition that used are flow rate that is 247, 280, 323, 382, 467 ml/minute and recirculation ratio 0.25; 0.50; 0.75; 1.00 and 1.25 by using BOD removal. The best result that is got from this study that is in flow rate 247 ml/minute with recirculation ratio 0.75 that remove BOD as big as 89.63 %. Key word : Domestic wastewater, RBC
