Rotating Biological Contactors Or BioDisk Treatment

This is a very enhanced technology consuming lot of energy. Here Rotating Biological contactors are medium for biological growth. The contactors are multiple disks attached with each other and submerged partially into water to be treated. The residence time inside gives the reaction time. The rotation lifts the effluent water and microbes on the surface do their job of decomposing them when surface comes out of water level.
