Demineralization is concerned with the removal of all dissolved mineral matter from water.
Most common applications involved with demineralization are:
boiler feed water (BFW), 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 a steam turbine is involved, a high degree of water purity, is mandatory to meet requirements of the turbine manufacturer,
pharmaceutical applications to comply with strict standards concerning the salt and microbiological content to be used in drugs preparation,
semiconductor/microelectronics industry to comply with very stringent specifications related to the miniaturization of the components,
chemical and petrochemicalsectors as a process fluid,
food & beverage as a raw material in the preparation of the products.
Demineralization can be roughly outlined in two different steps:
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 that features Mixed Bed Exchangers or Electrodeionization (EDI).
Cannon Artes can boast ample experience with ion exchange, membrane processes and polishing. This comes from designing a vast range of plants, and from answering the most varied problems in all the industrial sectors. Thus making Cannon Artes demineralization plants the norm in the evolution of water treatment.
