Purolite® MB3720

High Purity Water Purification
Purolite MB3720 mixed bed resin is ready to use, 1:1 chemical equivalent that is highly regenerated in the H+ and OH- forms. Purolite MB3720 resins are manufactured by a proprietary process that achieves the high purity for ultra-pure water. The cation and anion used in Purolite MB3720 are gel resins that are polymerized with a styrene-divinylbenzene matrix and functionalized. The resin beads are highly durable and resist fragmentation that can result in particle release in the treated water. In regenerable mixed beds, separation of cation-anion during backwashing is critical to prevent cross contamination of the resin with the wrong regenerant. The high product quality ensures that it is possible to achieve treated water of the highest purity - resistivity >18.2 megohm-com. Air mixing and, in some cases, resin transfer for external regeneration could also be tedious operations, if the wrong resin selection is made. Purolite MB3720 is specifically designed to meet these challenges, every time it is regenerated. Use of Purolite MB3720 also negates the need for an inert, providing more operating capacity to your working mixed bed.
