Treatment of Hke's M.A.M Hostel Wastewater by Three Stage Rotating Biological Contactor

Due to global civilization and industrialization, there is a great demand for the water. A small fraction of the same is utilized and rest is being generated as wastewater. The disposal of such wastewater into water courses creates an adverse impact on the human health, flora and fauna. With the introduction of precise effluent standards it is the responsibility of wastewater engineer to treat the wastewater to satisfy the requirements of receiving body. Hence the safe disposal of such wastewater either on land or water bodies is the most challenging task before the engineers. This project is study to show the general wastewater characteristics collected from the HKE’S M.A.M, hostel and also to treat by attach growth process. The attach growth process considered for treating wastewater is Rotating Biological Contactor (RBC) model. Result showed removal efficiency for 40% submerged Rotating Biological Contactor (RBC) for Biochemical Oxygen Demand was efficient for rotational speed of disc at 4rpm after treatment and are within desirable limits of effluent standards as per CPCB, New Delhi.
