Ion Exchange Resins

AllWater Technologies Ltd, in association with Purolite®, the world leading resin manufacturer, offer an extensive range of ion exchange resins for water treatment systems applications. This offer includes base exchange softening, dealkalisation, nitrate removal, organic scavenging and demineralisation.

In addition to the standard grades of strong and weak acid cation and strong and weak base anion exchange resins, monodisperse (uniform bead size) resins are also available, providing potentailly higher operating capacity with a lower pressure loss.

Ion Exchange Resins currently available include the following

Strong Acid Cation Gel
Polystyrenic, strong acid cation gel exchange resins are used in softening and demineralization of water and in other specialist applications. The products offer high physical strength and efficient operation over a wide range of operating conditions.

Ready to Use Mixed Beds
Ready to use mixed beds are specially prepared high quality resin mixtures designed for direct purification of water. The ratio of component resins has been specifically tailored to provide high capacity. Performance, of the ready to use mixed bed, will depend on the application.

Inert
IP1 and IP4 are inert plastic material beads with a specific gravity lower than that of water capable of floating just above the ion exchange bed. The use of a layer of this media improves the distribution of water and the collection of the spent regenerant in the top part of the vessel.
