The rotating biological contactor (RBC) was tested for treatment of aquacultural water in a pilot-scale recirculating aquaculture system. Performance of RBC on the treatment of nitrogen source such as total ammonia nitrogen (TAN), nitrite nitrogen and nitrate nitrogen and chemical oxygen demand (CODcr.) was evaluated. A system was stocked with nile tilapia at an initial rearing densities of and over 30 days. As increasing rearing density from to , the TAN removal rates was increased from to . But TAN removal efficiency was decreased from to . The removal rate of was higher than TAN. The RBC as an aerator was also evaluated for increasing dissolved oxygen concentration. For and of rearing density, the average aeration rate were and , respectively. |
