Purolite® UCW9964, LOW TOC Separable Mixed Bed Resin, H/OH Form is a separable mixed bed resin is ready to use, specially produced and cleaned for Ultra-Pure Water applications, 1:1 chemical equivalent that is highly regenerated in both the H+ and OH- forms. UCW9964 is manufactured in a proprietary process that achieves the ultimate purity for critical UPW applications such as semiconductor chip and wafer manufacturing. The cation and anion components used in UCW9964 are highly durable gel resin beads that resist fragmentation reducing particle release in the treated water. In regenerable mixed beds, good separation of cation-anion during backwashing is critical to prevent cross contamination of the resin with the wrong regenerant. After regeneration reduce the water level to 5 cm (2 inches) above the anion bed and air mix at 0.8 to 1.2 bar for 10 minutes ensures good mixing of the cation and anion resin. UCW9964 has been specifically designed to meet the challenges of performance and reliability critical to your working mixed bed.
