Spectrum Premium Softening Resin 25 Litres
This is high purity premium grade water softening resin. It is made from high purity bead-form of conventional gel (sodium polystyrene sulphonate) cation-exchange resin that removes hardness ions (calcium and magnesium) in exchange for sodium ions.
Being a gel type, this helps add extra capacity and strength to the resin. Regeneration of this resin is possible through the use of brine (salt) solutions.
|Model||Premium Softening Resin 25 Litres|
|In Depth||Its specification is such that it will exceed the relevant EEC requirements, and the resin is in compliance with the U.S. Food & Drug Administration Code of Federal Regulations section 21, paragraph 173.25; for use in the treatment of foods for human consumption. Its high bead integrity, excellent chemical and physical stability, and very low extractibles content play a large part in its successful employment in these areas.
