De-ionization is the removal or reduction of positive ions called cations and negative ions called anions from the water supply. High purity water from 1.0 to 18.3 megaohms/cm and a silica level of .10ppm to 0.01ppm or lower can be produced. The cation resin is converted to the hydrogen form and exchanges positive ions for hydrogen. The Anion resin is converted to the hydroxyl form and exchanges the negative ions for hydroxyl. Resins are designed specifically for deionizer applications regenerating with approximately 6.4 pounds of 100% of HCI per cubic foot for hydroxyl.
Resins are designed specifically for deionizer applications, and typically regenerating with 6.4 lbs of 100% HCI per Cubic foot of cation resin and 8.0 lbs. of 100% NaOH per cubic foot for anion resin. Lakeside resins provide high chemical and physical stability, lower pressure drop and greater resistance to bead breakage. Strong or weak base resins are selected based upon the customers water quality requirements. Type 1 or 2 Anion resins are selected based upon the silica residuals required for the specific application. Standard systems utilize pressure compensating educators for drawing chemical.
