Purolite® NRW37

Nuclear Grade Mixed Bed Exchange Resin
Purolite nuclear resins are processed to the most exacting specifications. They are specially purified to ensure high percentage conversion to their regenerated form, and are offered in closely controlled particle size ranges. All products in the Purolite range have whole perfect beads typically over 95%. They meet the specifications required by major engineering companies throughout the world. Purolite's nuclear products are used in the production of ultra pure water, preparation of condensate, radiation waste treatment and in the manufacture and purification of pharmaceutical products. Mixed bed resins are frequently used in polishers following other types of water treatment. The high product quality ensures that it is possible to achieve treated water of the highest purity - conductivity 0.055 µS cm-1 or resistivity 18.3 Meg Ohm.. The component resins of Purolite NRW37, Purolite NRW400 (strong base type 1 anion exchanger) and Purolite NRW100 (strong acid cation exchanger) are combined in the ratio which for general types of water to be treated yields the optimum exchangeable capacity. Other ratios are available on request. Purolite mixed bed resins can be used for both regenerable or non-regenerable (cartridge) systems.
