bioFAS™ B-460

Maximize your wastewater treatment efficiency with bioFAS™ B-460 Biomass Carriers. Specially designed for MBBR systems, these carriers facilitate a self-sloughing, auto-regulating biofilm treatment process, ideal for enhancing the capacity of existing activated sludge systems.


The bioFAS™ B-460 MBBR media is engineered for optimal performance in moving bed biofilm reactor systems. These carriers are adept at providing an efficient, self-regulating biofilm treatment process.

They are versatile enough for use in both single-pass MBBR treatment processes and as an enhancement to existing activated sludge systems through the Integrated Fixed-film Activated Sludge (IFAS) process. This adaptability makes them a valuable asset in various wastewater treatment scenarios.
