The biodegradation reactor comes in one or two stages depending on required cleaning efficiency. The bioreactors are degrading the dissolved organic matter by oxidation into carbon dioxide which escapes to the air, and to produced biomass which act as activated sludge. A suspended, free floating biofilm carrier medium is providing a large, protected biofilm surface as host for the bacteria and is simultaneously accumulating the active biosludge inside the reactors. The biodegraded water is flowing into a clarification stage where the suspended solids settles by gravity. The water is directed through a skim well to a plate settler system which provides the final clarification of the effluent For systems with high cleaning efficiency, the sedimentation may be enhanced by addition of polymers.
