AccuFAS Aeration Pattern

The Brentwood-engineered AccuFAS Submerged Fixed-Film system adds a fixed-growth surface for biomass to provide enhanced biological treatment and increase capacity for municipal and industrial wastewater. Composed of Brentwood’s structured-sheet, fixed-film media, AccuFAS was developed to optimize airflow and mixing while maximizing contact between the waste stream and biomass.

This video demonstrates aeration, which is a critical step in the biological treatment process that ensures sufficient oxygen is present for oxidation of carbonaceous BOD and ammonia. The AccuFAS system uses fine bubble diffusers mounted under the media towers to provide a high level of oxygen transfer efficiency and to circulate the wastewater by airlift pumping.
