INDUSTRIAL PROCESS WATER (I.P.W.)

A specific apparatus is associated to each treatment.

 General treatments - Dissolved salt removal

• Iron (by forced aeration or biological process)

• Manganese (by chemical or biological process)

• Ammonium, nitrite, nitrate (by chemical or biological process)

• Filtration on porous membranes

  • nanofiltration - retention de suspended solids, colloids, germs, viruses, and some bivalent salts, the monovalent salts are nearly removed.

    NANOSEP (Nano Filtration)

  • reverse osmosis - retention of nearly all ions, salts, germs, viruses, …

    • One-train unit

      PERMASEP

    • Multi-train unit

      • serial

        PERMASEP H.E (High Efficiency)

      • in parallel

        PERMASEP H.F (High Flow)

      • combinated (serial and in parallel)

        PERMASEP C. (Combination)

• Demineralisation (on ion exchange resins) :

  • exchanger with co-flow regeneration

• exchanger with reverse-flow regeneration

  • fixed-bed exchanger

    COMPACTBED

  • fluidised-bed exchanger

    BAYER SCHWEBEBETT

• single-resin bed exchanger

• multi-resin bed exchanger

  MIXHYDROBED

• exchanger with specific resins

• with or without CO₂ stripping tower
