Water is one of the essential resources to produce paper and cardboard. Ion exchange resins are used to produce power at the site, to reuse the water used during the production and to treat the waste water caused by the paper process. The reuse of water with ion exchange resins reduces the waste water, increases sustainability of the process and reduces the use of resources and increases the profitability.
Todays water quality discharge regulations requires a strict control and treatment of the waste water, Ion exchange resins are used to reduce ionic species in the waste water.
Treatment of condensate.
Demineralisation of Industrial Water
Removal of all ions from a water stream (salts and minerals) to lower conductivity
Mixed Bed (Polishing)
Demineralization treatment with a mixed bed resins (SAC + SBA) to remove residual ions salts and minerals after a demineralization system
Removal of total hardness (calcium and magnesium) from liquids
Strong Acidic Cation
Strong acidic cation resins are bead sized co-polymers (mainly polystyrene-divinylbenzene) with a sulfuric group which attracts cations. Resinex SAC comes in gel or macroporous types and are available in several bead sizes to adapt to different applications.
Strong Based Anion
Strong base anion resins are bead sized co-polymers (mainly polystyrene-divinylbenzene) with a tertiary or quaternary ammonium group which removes anions in various processes. Resinex SBA comes in gel or macroporous type and is available in different bead sizes.
These are non-functionalized inert media made from Polypropylene or Polyethylene to protect tank nozzles or act as layers in packed beds and mechanical filters.
Mixed Bed Resins
Mixed bed resins are composed of strong cationic and anionic ion exchangers based on a polystyrene-divinylbenzene matrix that are usually sold in the ready to use (active) ionic forms.
W A C
WAC are polyacrylic, gel or macro ion exchange beads. They have the unique carboxylic acid functions.
Weak Based Anion
Weak base anion resins are bead sized co-polymers (mainly polystyrene-divinylbenzene) with tertiary ammonium groups, which are usually macroporous in structure.
