CD Plant 3

Byelorussian Steel Works

To treat the concentrate from an existing steel production wastewater treatment plant, the following treatment layout has been installed at the Client’s site:

  • chemico-physical pretreatment
  • pressurized multimedia granular filtration
  • anti-scalant dosing
  • cartridge filtration
  • CD-RO membrane filtration (first pass)
  • spiral-wound RO membrane filtration (second pass)

mft CD-RO modules are essential to maximize the overall recovery rates, thus reducing the size and the operating costs of the following evaporation unit (ZLD process)
