Situation
• Rising waste water costs
• Exceeding of waste water-relevant limits
• Inadequate elimination of harmful substances by means of conventional
  sedimentation tank technology
• Accumulation/disposal of heavy metal sludge
• Loss of valuable (recoverable) materials
• Unutilised savings potentials

BFI solutions
• Methods for prolonging the life of surface treatment process baths and
  rinsing water
• High-power bio-reactors and bio-membrane processes to minimise
  surplus sludge production
• Electrodialysis and membrane electrolysis for electrolyte treatment
• Reduction of organic contamination through upgraded oxidation
  processes (AOP) such as UV + hydrogen peroxide
• Electrochemical adsorbent regeneration
• Recovery of valuable metals by means of liquid extraction
• Recovery of spent pickling acids by means of microfiltration, nanofiltration
  and electrodialysis
• Emulsion separation in a countercurrent reactor using organic agents
  (BFI oil concentrator)
