Biostyr® Biological Aerated Filter (BAF) is a compact wastewater treatment system made from polystyrene beads in a submerged media bed, designed for municipal and industrial wastewater treatment where space is limited and a low environmental footprint is needed.

  • Compact biofilter system for treating municipal and industrial wastewater
  • Small footprint suitable for sites with limited space or close to residential areas
  • Modular design allows for easy expansion and adaptation to load changes
  • Gravity backwash system reduces equipment and maintenance needs
  • Fully automated operation for simplified management
  • Handles both soluble and particulate pollution without final clarification
  • Adaptable for carbon removal, nitrification, and denitrification processes

Applications

  • Municipal wastewater treatment
  • Industrial wastewater treatment
  • Sites with limited available space
  • Plants near residential neighbourhoods
  • Tourist and resort areas
  • Mountainous or weather-exposed locations

Materials

Made from polystyrene beads (Biostyrene™)

Performance

Removes chemical oxygen demand (COD), biochemical oxygen demand (BOD), ammonia (N-NH4), nitrate (N-NO3), and total suspended solids (TSS)

High tolerance to load variations

Installation

Gravity backwash using treated water stored in the upper structure

No wash pump required

Maintenance

Reduced maintenance due to gravity backwash and fewer installed components
