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.
Industrial Water Equipment Ireland are able to offer ion exchange resins for a wide variety of applications. Please contact us with your requirements.
Ion Exchange Resins Explained
An ion-exchange resin or ion-exchange polymer is an no soluble matrix (or aid structure) commonly available as tiny (1-2 mm diameter) drops, typically white-colored or even yellowish or golden-tinged, fabricated through the natural and organic polymer substrate.
The fabric contains an extremely formulated shape of pores on the actual area which are used with easily caught as well as released ions. The capturing of ions occurs simply using synchronised release of additional ions; therefore this process is termed ion-exchange. You will discover a variety of different kinds of ion-exchange resin which can be fabricated to uniquely choose a single or even numerous distinct ions.

Ion-exchange resins are usually used in numerous separation, refinement, as well as decontamination functions. Probably the most widespread illustrations tend to be water treatment and water refinement. Many times ion-exchange resins have been presented in such processes as a much more versatile option to the usage of organic or even manufactured zeolites.
Commonest ion-exchange resins provide crosslinked polystyrene. The necessary active groups are usually presented right after polymerisation, or even substituted monomers may be used. For instance, the crosslinking is usually accomplished with the addition of .5-25% of divinylbenzene to styrene within the polymerization procedure.
Non-crosslinked polymers are utilized infrequently simply because they're much less stable. Crosslinking reduces ion- exchange capability of the resin as well as extends any time required to achieve the actual ion exchange processes. Particle dimension additionally affects the resin parameters; more compact particles possess a larger area, yet result in greater head loss within the column processes.
Aside from being created as bead-shaped substances, ion exchange resins are usually developed as membranes. The membranes are created of hugely cross-linked ion exchange resins which permit passing of ions, although not of water and tend to be employed for electrodialysis.
Presently thereare 4 primary kinds varying within their working groups: highly acidic, highlybasic, weakly acidic, weakly basic.
