AGAR - Model RF -Roughing Filter System

The AGAR® RF (Roughing Filter) MBBR consists of two biological stages: a preliminary small volume AGAR®MBBR reactor followed by AS (Activated Sludge). This configuration utilizes the MBBR capability to significantly reduce wastewater organic load in a relatively small reactor volume filled with Aqwise Biomass Carriers, followed by the high-quality effluent achievable in an activated sludge system. The initial MBBR phase drastically reduces the high organic load in a relatively short retention time (which translates into a small footprint), and the final reduction of pollutant levels is achieved in the following activated sludge phase. Besides offering an overall footprint reduction compared to an equivalent activated sludge system, the AGAR® MBBR offers a buffer against shock loads or inhibitory substances, protecting the downstream activated sludge from process upsets.
