Deionization 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 megohms/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. This ion exchange process removes the majority of the dissolved minerals and produces deionized water (H2O). Mixed bed systems utilize a single tank with thoroughly mixed resins. A mixed bed system produces a higher quality of deionized water compared to a two bed system. Ion exchange does not reduce the bacterial count of the water.
Resins are designed specifically for deionizer applications regenerating with approximately 6.4 pounds of 100% of HCI per cubic foot for cation resin and 8.0 pounds of 100% NaOH per cubic foot for anion resin.
Resins provide high chemical and physical stability, lower pressure drop and greater resistance to bead breakage..
Type 1 Anion resins are standard to produce the lowest silica leakages and 10% cross-linked cation resins for durability and performance.
Standard Cation regeneration is with 32% HCl.
Standard systems utilize pressure compensating for drawing chemical.
Low maintenance and installation cost.
