BioCube is a self-weighted retrievable fixed film stationary media module pre-engineered as a high rate air-lift reactor for enhanced BOD and/or ammonia removal. This equipment consists of a vertical channel biofilm support media in honeycomb arrangement combined with OxyStrip strip diffusers for optimized air supply and uniform scouring of excess biomass.

BioCube's hydraulic design creates a rolling flow pattern around the cube and supplies the active biomass with oxygen and substrate and prevents growth of inactive biomass, clogging and red-worms at the same instant. BioCube increases activated sludge reactor BOD removal capacity by up to 60% by volume compared to conventional suspended biomass reactors.
