BBF Biofiltration


Tomorrow Water’s BBF BioFiltration platform is an advanced wastewater treatment technology that combines biological treatment and physical filtration in a single reactor.

With over 50 references worldwide, Tomorrow Water’s BBF BioFiltration system is a versatile, innovative, and proven technology.


The BBF biofiltration system can be used for primary, secondary, and tertiary treatment. By combining physical filtration and biological treatment, BBF applications range from large scale municipal wastewater treatment to high strength livestock wastewater.

  • Primary & Combined Sewer Overflows (CSO) Treatment

  • Physical and Biological Filtration

  • Secondary and Tertiary treatment for Nitrogen Removal

  • Municipal, Industrial and Groundwater Treatment

  • Concrete and Steel Vessel


Generally, biofiltration technology is used for secondary and tertiary treatment.

Tomorrow Water has continuously expanded the application of BBF to primary & wet weather flow treatment through upgrading our key components such as media and strainer blocks. Additionally, BBF can treat groundwater through strengthening of biological function of BBF.

  • Special Media Maximizing Surface and Porosity

  • Specialized Strainer Block and Nozzel

  • Conventional (BNR) and Advanced (Anammox) Nitrogen Removal 


With over 50 references worldwide, the BBF BioFiltration system comprises a range of proven and versatile solutions optimized for the treatment of municipal wastewater, groundwater, and high-strength industrial wastewater.


Previously certified for compliance with CA Title 22 water reuse regulations, BBF is not only suitable for the upgrading and retrofitting of existing wastewater treatment plants, but also for integration into new wastewater reuse facilities. Recognized by WERF’s LIFT Program as a substitute for the primary clarifier, BBF can also remove solids and soluble organics for carbon diversion and to control wet weather flow.

  • More than 50 references

  • Large scale experience(upto 190 MGD)
