Abstract:

The laboratory model of the two-stage Rotating Biological Contactor (RBC) used in the present study is a modified one, with a provision to vary the speed of rotating blades. Grey wastewater was used to study the performance of the modified rotating biological contactor. The reactor had four rotating blades in each stage, having 300 mm x100 mm x 10 mm, attached perpendicular to the shaft. The experiment was conducted for different influent COD loads and different speeds of rotating blades. Mathematical Models, Kornegay models, and Hudson models were used to evaluate the kinetic coefficients to describe RBC kinetics for treating greywater.

Keywords:

RBC; rotating blades; Greywater; COD; OLR.
