Reverse Osmosis, Water Hygiene, Water Softeners, Water Filtration and Effluent Treatment from Industrial Water Equipment Ltd

Ion Exchange Resins Clean, high-purity water is demanded by all sectors of society. However conventional filtration methods fail to remove many of the dissolved, unseen contaminants found in water, especially those in ionic form.

The importance of high-purity water is especially prevalent for major industries, with practical uses in applications that include: - wash & rinsing, beverage and food services, pharmaceutical, and semiconductors. This creates a need for ion-exchange resins, which prove to be both an effective and economic format for water softening and high purity applications.

Suitable for use in regenerable or non-regenerable cartridges, or in high capacity pressure vessels, several grades of resin are available and are supplied in 25 litre bags.

DEIONISATION RESINS

MB400 - ready to use mixed bed resin

This high quality mixed bed resin consists of a strong acid cation and strong base anion mixture, to create pure demonized water. MB400 is capable of producing high-purity water with low conductivity values, and suitable for applications where typically a water quality of 0.1 microSiemens/cm is required.

The applications and industries include :- chemical and photographic labs, water conditioning for steam irons, top-up of car batteries, stain prevention in the glazing industry, cleaning of glassware, window washing/water fed poles for a spot free rinse, and in hospitals.

The resin life is maximised when used as a post-polisher after a reverse osmosis or deionisation plant, and suitable for use in regenerable or non-regenerable cartridges, or in large ion-exchange units.

NRW37 - Nuclear grade mixed bed resin

Nuclear grade mixed bed DI resins are used for the production of ultra-pure water, ensuring the the water treated is of the highest purity possible. Manufactured from strong base type 1 anion and strong base acid cation mix, the NRW37 resin insures that thy water processed is of highest quality 18.3 magaohm resistivity, or 0.055 microSiemens/cm conductivity.

The high resistivity water produced by NRW37 is suitable for many high end applications and industries, which include - ultra-pure water production, radiation wastewater treatment, manufacture and purification of pharmaceutical products, semiconductors and condensate polishing. This nuclear grade resin is processed under the most exacting specifications being specially purified with high percent conversions to their regenerated form, and closely controlled particle sizes.

All of Purolite's nuclear grade products have over 95% whole perfect beads. which creates a product with low differential pressure drops, increased stability that is less likely to breakdown, and consistent performance.

MB500IND - Self-indicating ready to use mixed bed resin

Exhibiting the same deionisation characteristics as the MB400, the MB500IND contains an indicator, which shows when the resin is exhausted and no longer has the capacity to treat the water. The resin will change colour from blue/green to cream once its capability has been reached.

This colour change is distinctive making the MB500IND resin ideal for use with opaque canisters, or in low light areas. MB500IND is suitable for use within regenerable and non-regenerable applications.

MB59VC - Partial deionisation mixed bed-resin

This self-indicating resin will change colour from green to blue once exhausted. Manufactured from a strong gel cation, and weak base macroporous anion mix, MB59VC offers partial deionisation to an acceptable level for most non-critical applications. Silica and bicarbonate will not be removed from the water by MB59VC during the exchange process.

WATER SOFTENING RESINS

C100E - Strong-acid Cation-exchange resin

Ideal for use within both commercial and industrial applications, C100E is designed for treatment of food stuffs, beverages, potable water and food processing application. Its high bead integrity, excellent chemical and physical stability, and very low extractable content, play the key role in the resins success in the above applications.

C100E is high purity, premium grade bead-form of conventional gel (polystyrene sulphonate) cation-exchange resin, removing hardness ions (calcium and magnesium) in exchange for sodium ions.

Being of gel type, helps add extra capacity and strength to the resin. Regeneration of C-100 is possible through the use of brine (salt) solution.

C107E - Weak-acid Cation-exchange resin

C-107E is a macro-porous, high-purity, high-capacity poly acrylic weak-acid cation-exchange resin developed for the treatment of potable water. This food grade resin is especially suited for the removal of bio-carbonate alkalinity in water treatment, with major uses for dealkalisation and softening of water.

Hardness reduction and a lower pH are achieved, eliminating potential scum or scale formation when the water is used for residential purposes, or in the processing of food and beverages.

In addition to water softening, C-107E has excellent selectivity for heavy metals, and the uptake of alkaline earth metals in a relatively short contact time. Removal capabilities also extend to toxic metals, making the resin suitable for the treatment of certain wastewater applications. This resin is not suitable for regeneration.
