Moving Bed Biofilm Reactor (MBBR)

Aerobic & Anoxic Treatment System

How the PEWE ASO® Bio-Carrier Moving Bed BioReactor Works

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 PEWE US Patented (#D827765)  plastic media which provides a suitable home for biological colonies of bacteria and protozoa to grow and flourish. The ASO®Bio-Carrier media 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, typically for BOD/COD reduction. If de-nitrification is needed, mechanical agitation will be applied in place of aeration creating the necessary anoxic environment. The ASO®Bio-Carrier Moving Bed BioReactor is a flexible biological platform with easy future expansion—just add media.

PEWE ASO® Bio-Carrier MBBR Package Plant- Aerobic Treatment System for Soluble Organics

A complete integrated PEWE aerobic biological treatment system or ASO® Bio-Carrier MBBR water treatment system is a great tool for reducing soluble organics, BOD and COD. The package plant system typically consists of an initial SuperSkreen®, an equalization/pH tank, the ASO® Bio-Carrier MBBR media contained within one or more vessels with redundant blowers, PolyAccu Dose® nutrient and polymer feed station. Clients have a choice of dissolved air flotation between the HD2XLRator®, Nx2JEM®, T2-MAX®, Poly-E2® or the new Dueler® DAF unit for final clarification. The entire MBBR water treatment package is controlled with a state-of-the-art Command Control®automation panel with color touch-screen operator interface. This flexible design feature allows for a small footprint at new installations or upgrades to existing systems.

ASO®Bio-Carrier MBBR system 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 systems. 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. Consult your PEWE Client Systems Engineer with your specific biological needs.
