MAIN STEPS OF THE TECHNOLOGY

  • Coagulation
  • Flocculation
  • Lamella separation with sludge handling to minimize wastes
  • Sand filtration – additional suspended solid removal
  • Nano-filtrataion
  • Softening
  • Reverse osmosis 1. (RO1)
  • Reverse osmosis 2. (RO2)
  • treatment of brine of RO1 to minimize wastes
  • Regeneration of softener with brine of RO2
  • Heavy-metal separation with ion-exchanger (IX)
