  • expensive water or waste water discharge costs in the customers site
  • strict limits for waste water discharge
  • not any possibility for waste water discharge

Principles:

  • Zero discharge - partially
    • Recycling portion of waste water
    • Decreasing production of waste water
  • Zero discharge - fully
    • Recycling all waste water
    • Zero water discharge
  • With the use of
    • Ion exchangers
    • Membrane processes
      • Microfiltration
      • Ultrafiltration
      • Reverse osmosis
    • Vacuum evaporators
