AquaCELLTM is a moving bed biofilm reactor (MBBR) process in which millions of submerged polyethylene (HDPE) biofilm carriers operate in motion within an aerated or mechanically mixed basin. Each carrier element incorporates multiple cells of protected surface area to sustain a dense community of attached growth fixed-film microorganisms (heterotrophic and autotrophic bacteria). As the neutrally buoyant carriers move throughout the water column, oxygen and organic/inorganic material are available to the biofilm which absorbs, oxidizes and reduces these pollutants thus providing treatment. The dense population of bacteria provides high-rate productivity, enhanced nitrification/denitrification, process stability, small footprint and ease of operation.
Ease of Operation and Maintenance
AquaCELLTM MBBR is a one-pass process eliminating the need to manage the MLSS, Food to Microorganism ratios and return activated sludge (RAS) associated with conventional suspended growth systems.
The MBBR process is not only resilient in toxic shock loading and extreme temperature conditions but it is also self-purging and naturally responsive to fluctuations in organic and nutrient loading. Potential “wash out” events from hydraulic surges are eliminated as the biofilm resides on the media retained in each reactor basin.
Typically 25% to 50% of the size of conventional systems
System capacity can be increased with greater biofilm carrier fill fraction
Enhanced Oxygen Transfer Efficiency
As oxygen bubbles ascend in the water column, the biofilm carriers act as a shearing device to enhance oxygen transfer.
Retrofit Any Treatment Process
Separate stage MBBRs may be added to lagoons, RBCs, SBRs, etc. for roughing, nitrification and/or denitrification while an “in the soup’ integrated fix-film activated sludge (IFAS) upgrade is more common for conventional activated sludge systems.
Wide Range of Process Applications
Industrial and high strength waste streams; roughing reactors; tertiary anoxic denitrification reactors; sites requiring minimal management and oversight; lagoon, oxidation ditch, and RBC upgrades; cold climate nitrification/denitrification; slow build out developments (will perform at a very small fraction of design flow).
