PEWE MBBR — Aerobic Treatment System For Soluble Organics
The ASO Bio-carrier Moving Bed BioReactor (MBBR) is a standalone wastewater treatment system used for the reduction of soluble organics and nutrients. The key to the system is the plastic media which provides a suitable home for biological colonies of bacteria and protozoa to grow and flourish. The ASO Bio-carrier moving bed biofilm reactor technology is a straightforward flow through design with no sludge recycling or backwashing is necessary. The media are contained within the vessel(s) and mixing energy is applied via coarse bubble aeration. If de-nitrification is needed, mechanical agitation will be applied in place of aeration. The MBBR is a flexible biological platform with easy future expansion—just add media.
Operational control parameters are relatively simple. All that is required is monitoring of DO (keep above 2ppm) in the reactor via continuous automated control; test the daily organic COD feed (proxy for BOD); and dip strip check the nutrient levels in system. The several installation options ensure maximum exposure of MLSS to the media. The bacteria adhere to the media while digesting waste from the plant effluent stream. The result is a resident population of biomass that removes BOD and COD efficiently.

Typical MBBR Installation — Package Plants Simplify Process
The complete integrated ASO Bio-carrier moving bed biofilm reactor system package generally consists of an initial SuperSkreen®, equalization/buffer tank, the MBBR vessel with dual blowers, PolyAccu Dose® nutrient and polymer feed station. Clients have a choice of dissolved air flotation with the PEWE HD²XLRator®, Nx²JEM®, T²-MAX®, Poly-E²® or the new Dueler® DAF unit. The entire package is controlled with a state-of-the-art Command Control® PLC with color touch-screen operator interface. This flexible design feature allows for a small foot print at new installations or upgrades to existing systems. Consult your Client Systems Engineer with your specific biological needs.
