DEMINERALIZATION IS CONCERNED WITH THE REMOVAL OF ALL DISSOLVED MINERAL MATTER FROM WATER.
MOST COMMON APPLICATIONS OF DEMINERALISATION:
- Treatment of Boiler Feed Water (BFW), in order to maintain high heat-transfer efficiency in the boiler by preventing deposition of precipitated scale and corrosion or deterioration of surfaces in contact with water.
- When production of steam is related to power generation through a steam turbine, a higher water quality is mandatory to meet requirements of the turbine manufacturer.
- Chemical and petrochemical sectors where it is used as a process fluid.
Demineralization can be roughly schematised in three different steps:
- Pretreatment, possibly featuring Water clarification, In-line clarification, Media Filtration, GAC adsorption, membrane separation (Microfiltration, Ultrafiltration)
- Deionisation that could be achieved through Ion Exchange or Reverse Osmosis often coupled with atmospheric or membrane degassing to remove the residual carbon dioxide.
- Polishing featuring Mixed Bed Exchangers or Electrodeionization (EDI)
ON THE MARKET SINCE 1958, ARTES CAN BOAST LONG EXPERIENCE WITH ION EXCHANGE AND MEMBRANE PROCESSES. THIS COMES FROM DESIGNING A VAST RANGE OF PLANTS, AND FROM ANSWERING THE MOST VARIED PROBLEMS IN ALL INDUSTRIAL SECTORS WHICH HAS MADE BONO DEMINERALISATION PLANTS THE NORM IN THE EVOLUTION OF WATER TREATMENT
