Bagasse is a cheap material and the collection of bagasse is easy from sugarcane shops. This survey used cane bagasse as a substrate for aerobic biological modeling to treat aquatic waste water, bringing about economic, technical and environmental benefits. This study was conducted at three different loads: COD/m3 .day; COD/m3 .day; COD/m3 .day. The results showed that COD removal efficiency was , the optimum load of the research model was COD/m 3 .day for the SS removal efficiency reaching . | Survey on the ability of cod and SS treatment of aquatic waste water by aerobic biological technology with bagasse substrate
