bioFAS™ B-585

Elevate wastewater treatment effectiveness with the bioFAS™ B-585 Biomass Carriers. Designed for MBBR systems, these carriers optimize biofilm processes, enhancing the capacity of both single-pass and IFAS applications.


The bioFAS™ B-585 MBBR media offers a cutting-edge solution for moving bed biofilm reactor systems.

These biofilm carriers are crafted to enable a self-sloughing, auto-regulating attached growth biofilm treatment process. Suitable for single pass MBBR treatment processes or for augmenting the capacity of existing activated sludge systems through Integrated Fixed-film Activated Sludge (IFAS), the bioFAS™ B-585 Biomass Carriers present a versatile and efficient solution for wastewater treatment.
