Abstract
The present invention provides an apparatus and method for biologically treating fluids, in particular municipal or industrial wastewater or the like, the apparatus comprising a pair of reservoirs each containing growth medium having a biofilm thereon, the apparatus being arranged to pump the wastewater from one reservoir to another such as to alternatively expose the biofilms within the reservoirs to air and wastewater, thus making it possible to achieve sequential aerobic, anoxic and anaerobic conditions in the biofilms.
