It is fully regenerated, ready-to-use, pre-mixed resin developed for the production of high- purity water in working and mixed bed polishing applications. The pre-mixed resin also allows for faster initial rinse-up prior to service, which minimizes rinse wastewater volume. AMBERLITETM MB20 H/OH is most commonly used in service deionization for a full demineralization of water when complete removal of silica and CO2 is required. In most of the applications, the conductivity of the treated water is much lower than 0.1 μS/cm and the pH is neutral. If necessary, the resin can be regenerated after exhaustion. Both components must be separated by backwashing and regenerated separately. AMBERLITE TM MB20 H/OH is the reference mixed bed for service deionization. The resin mixture is prepared from high-quality components and the proprietary manufacturing process ensures consistency from batch to batch. This enables the resin to perform in a highly stable manner delivering high-quality treated water consistently in both working and polishing mixed beds. The consistency in quality combined with visible separation of cation and anion resins prior to regeneration make AMBERLITE TM MB20 H/OH a trusted choice for mixed bed pool systems. Applications Service deionization System Designs Historical Reference Working mixed bed on tap water in small installations Mixed bed polishing on RO or demineralized water Extemally-regenerated mixed beds Non-regenerated mixed beds AMBERLITETM MB20 H/OH Ion Exchange Resin has previously been sold as AMBERLITETMM MB20 Ion Exchange Resin.

Operating Capacity The operating capacity of AMBERLITE TM MB20 H/OH Ion Exchange Resin can be estimated using the following formula, which gives an approximate determination of volume of water that can be treated: BV = 500 TDS (meg/L) or gal/ft3 187000 TDS (as ppm CaCO3) where BV (Bed Volume) is the number of liters of a feedwater containing a TDS (Total Dissolved Solids) given in meq/L that can be demineralized with one liter of the resin mixture when run to exhaustion (or US gallons per cubic foot of the resin with TDS as ppm CaCO3). Treated Water Quality AMBERLITETM MB20 H/OH Ion Exchange Resin provides a high-quality demineralized water with a conductivity < 0.1 μS/cm and neutral pH that will satisfy most of the cartridge and laboratory applications. Suggested Operating Conditions Hydraulic Characteristics Temperature Range (H/OH form) + pH Range 5-60°C (41-140°F) 0-14 *Operating mixed beds at elevated temperatures, for example above 60-70°C (140-158°F), may impact the purity of the loop and resin life. Contact our technical representative for details. For additional information regarding recommended minimum bed depth, operating conditions, and regeneration conditions for mixed beds (Form No. 177-03705) or separate beds (Form No. 177-03729) in water treatment, please refer to our Tech Facts. Estimated bed expansion of the cation component (Figure 1a) and of the anion component (Figure 1b) of AMBERLITE TM MB20 H/OH Ion Exchange Resin as a function of backwash flowrate and temperature are shown. Estimated pressure drop for AMBERLITE TM MB20 H/OH as a function of service flowrate and temperature is shown in Figure 2. These pressure drop expectations are valid at the start of the service run with clean water and a well-classified bed.
