ABSTRACT

 

Conventional rotating biological reactor was modified to enhance the effective surface area of the treatment by providing plastic scrubbers filled rotating drums instead of discs. In the model developed at the laboratory baffles were provided with perforations. Two baffles were filled with media for enabling extra biofilm growth which resulted into better performance of model. Quality parameters of effluent were studied after conducting the series of experiments for the analysis of BOD and COD. When the model was operated for a detention time of 24 hours and rotational speed of 3rpm great reduction in BOD and COD of fed wastewater was observed and the values were 69% and 67% respectively
