Situation
• Accumulation of interfering components (solids, metals) and acid depletion
  in pickling process baths
• Reduced plant and equipment availability due to
  bath disposal and replacement
• High demand for fresh acid; spent acid from continuous processes
• Unsteady pickling bath concentrations
• Accumulation of scale in the pickling bath
• Cost-intensive disposal of spent acids and sludge
• High water consumption in the cleaning brushes and rinsing zone

BFI solutions
• Reduced fresh acid demand and waste acid output by means of 
  acid regeneration
• Constant pickling bath concentrations by means of online analysis 
• Solids separation by means of microfiltration
• Reduced rinsing water consumption by means of cascading
• Reduced water consumtion in cleaning brushes by means of water recycling
