Deionization or demineralization is a chemical process that forms high purity water by removing all charged particles in raw water using an ion-exchange method. Demineralization or deionization produces water that is similar in quality to distilled water, we produce strong base anion gel and macroporous types, weak base anion porous types, with fine mesh resins, coarse mesh or design mesh resins.
Strong Base Anion (SBA) exchange resins based on a polystyrene or polyacrylate matrix with gel or macroporous structures, including Type I with a trimethyl ammonium group and Type II with a dimethylethanol ammonium group. Because of pore structure, macroporous resins have better resistance to osmotic shock attrition, better access to the active sites, and greater resistance to fouling due to the large surface area.
Weak Base Anion (WBA) exchange resins with functional group of the tertiary amine, including polystyrenic or polyacrylic matrix, also have gel and macroporous types. Weak base anions are more chemically stable than strong base anions and are used for the removal of mineral acids, organic acids and other organic materials. They are highly resistant to organic fouling.
