(Bio2Bloc) : FBC Technologies Bio2Bloc was developed for aerobic wastewater retention basins, tanks, or lagoons that can benefit from fixed-film treatment
The Bio2Bloc system has been in service since 1999 in municipal and industrial WWTPs. The system has performed successfully in removing BOD and ammonia-where alternatives would have been too expensive or have taken too long to implement. The Bio2Bloc provides a rich and stable environment to bolster your existing microorganisms. Unlike an RBC, the aerated media beds are in constant contact with the water and are completely aerated by a highly efficient aeration system.
Each Bio2Bloc is filled with thousands of pieces of bio-media where, during normal operation, a healthy biomass is formed by a supply of air and water produced by the fine bubble membrane diffusers located on the bottom of each bio-chamber. As with any fixed-film biological contactor, the units will tend to become overgrown with organisms after a period of time. When this happens, it's time for back-flushing! The patented Bio2Bloc has a separate coarse-bubble system, valved from the shore, to slough the media bed and clear the chamber for renewed growth.
Bio2Bloc are designed to be deployed individually or in series to remove pollutants. They diffuse a high level of dissolved oxygen into surrounding wastewater through the media bed. The units are built to specification and are easily installed using a light-duty boom truck and floated into place.
