GRG - Rotating Biological Contactor (RBC)

RBC is rotated slowly by an electrical motor (geared box) & is arranged in the bioreactor tank in such a way that its half portion is always submerged in the effluent/ sewage. The RBC rotates, the surface of the media is subjected alternately to wastewater/ Sewage and air which encourages an aerobic digestion of organic matter & forms biologically active film of micro-organisms (biomass).
