A process for treating organically contaminated waste water is provided comprising an initial treatment step whereby microorganisms are replicated and either attach to support media or remain suspended in the waste water. The microorganisms reduce the incoming biochemical oxygen demand (BOD) level by consuming the organic contaminants. At least a part of the suspended portion of microorganisms are subsequently removed from the initially treated waste water, and the waste water under goes a further treatment step to further reduce the level of organic contaminants.
