Situation
• Limited operation time of degreasing, rinse and pickling liquors
• Discontinuous operation limits the availability of treatment plants and
  causes process fluctuations
• Waste water formation
• Disposal costs caused by spent acids, rinse water, neutralisation sludge

BFI solutions
• Operation time extension of process liquors
• Effluent free production and waste prevention
• Maintance of degreasing liquors 
• Rinse water treatment
• Maintance of rolling emulsions
• Metal rcovery

Services and equipment
• Process development and application technology
• Membrane and chemical laboratory
• Mobile pilot plants for on-site application
• Pilot scale plants for process development and selection of membranes
