Situation
• Inadequate removal of undesirable, dissolved, biologically degradable
  components by chemical/physical methods (e.g. flotation)
• Long hydraulic residence time in biological treatment facilities
• Insufficiently low bacteria concentrations in existing treatment facilities
• Occurrence of foam/scum/bulking sludge problems
• Bacterial contamination of cooling water and emulsion recirculation
  systems

BFI solutions
• Process-related optimisation of biological treatment facilities
• Development of new processes or combination of existing ones to treat
  problematic process water types
• Innovative process concepts, e.g. membrane bio-reactor
• Testing and implementation of process concepts in laboratory and
  field experiments
• Use of e.g. selectors to avoid foam/scum/bloating sludge
