The differences between fixed and moving bed systems are significant, as discussed in the four previous blog articles. Therefore, a comparison ...

The aeration design for a biofilm system, such as moving bed or AccuFAS fixed-film systems, is more complex than a standard activated sludge system. ...

The specific surface area of moving bed media is reported to be roughly 150 ft2/ft3 (500 m2/m3). Brentwood’s fixed bed system, AccuFAS, has a ...

Submerged fixed-film media is utilized within aeration basins to optimize biological treatment and increase capacity. Therefore, proper design and ...

Aeration basins can have length to width (L:W) ratios varying from 1:1 (square) to over 30:1 (plug flow). The L:W ratio of an aeration basin directly ...

Submerged fixed-film systems are ideal for significantly increasing nitrification in existing wastewater treatment plants. A well-designed and ...

We’re often asked how our AccuFAS system compares to other submerged fixed-film systems, such as MBBR and fabric media. To answer such ...
