This specialized mixed bed matrix combines crosslinked divinylbenzene-polystyrene gel beads formulated with sulfonic acid and Type I Quaternary Ammonium functional groups. Shipped fully regenerated in the active H⁺ and OH⁻ ionic forms at a strict 40:60 volumetric ratio, it provides full mineral acid and cation retention, eliminating baseline impurities while exhibiting exceptionally low pressure drop characteristics. Compliant with international regulatory frameworks, the material holds official IFANCA Halal certification, guaranteeing safe integration into standard industrial food, beverage, and electronics manufacturing facilities. Purolite MB400 functions flawlessly in both coflow and counterflow systems, as well as working mixed bed configurations, providing a cost-effective path to clean, high-resistivity water processing.
Removal Capabilities:
Total Dissolved Solids (TDS) Deionization: Complete extraction of scale-forming Cations and mineral acid Anions to produce high-purity, demineralized process water.
Silica and Carbon Dioxide Reduction: Effectively traps weak acids and residual trace minerals under standard working mixed bed operational profiles.
