ABSTRACT

 

Biological wastewater system is an integral part of wastewater treatment with measure role of beneficial microorganism. Rotary Drum Reactor (RDR) is a technique of using attached and suspended growth system by effectively using the advantages of both systems. The experimental model was developed representing the combined growth system. Outer unit represents suspended growth system and inner unit represents attach growth system. It was operated at different rotating speed to optimize the performance. Optimum performance showed efficiency of wastewater to be 75% of COD, 85% of BOD and 80% to 85% of TS.
