The water demineralization
All ions must be removed from water. Therefore the water passes first through cation exchange resins in the hydrogen form, then through anion exchange resins in the hydroxyl or free base form. All cations are replaced by ions from the cation resin, and all anions for the ions of the anion resin. These H+ and OH— ions recombine to create new water molecules (H2O). The treated water contains only traces of sodium and silica.The use of weakly functional resins depends on the raw water analysis and plant size.
The Quentin process in sugar decolorization
Crystallisation of beet sugar is partially inhibited by the potassium and sodium ions contained in the juice, so that large quantities of sugar remain in the molasses after crystallisation. Magnesium being less "melassigenous" than sodium or potassium, the idea is to pass the thin juice through a column of strongly acidic cation exchange resin in the magnesium form. This increases the production of whit sugar and reduces the quantity of molasses.
