bioFAS™ B-700

Introducing the bioFAS™ B-700 Biomass Carriers, specifically designed for advanced moving bed biofilm reactor (MBBR) systems. These carriers facilitate a self-sloughing, auto-regulating biofilm process, ideal for enhancing treatment efficiency in various wastewater systems.


The bioFAS™ B-700 MBBR media is a breakthrough in biofilm carrier technology. Perfect for application in MBBR systems, these carriers are engineered to provide a self-sloughing, auto-regulating attached growth biofilm treatment process.

They are versatile enough for upgrading existing extended aeration systems, single-pass MBBR treatment processes, or increasing the capacity of existing activated sludge systems through the Integrated Fixed-film Activated Sludge (IFAS) process.
