The AGAR® Roughing Filter for Biological Nutrient Removal (MBBR-BNR) configuration offers a treatment process based on a bio-film which provides organic carbon removal, followed by nitrification and de-nitrification, without circulation of activated sludge. Denitrification occurs in both pre-denitrification reactor, and in an innovative, patent pending, fixed/moving bed reactor in which intensive endogenous denitrification occurs.
The process is simple, robust, and requires minimal operator intervention. Wastewater is introduced into a multiple-stage system, each of which contains the suitable volume of AqWise Biomass Carriers, followed by the fixed bed reactor.
The MBBR-BNR configuration is extremely well suited for small and medium municipal applications, where nitrogen removal is required with a minimal operator intervention. |
