What is dowex used for?
What is dowex used for?
In short, DOWEX UPCORE™ is an ion exchange system that can help your industrial facility increase the flow of demineralized water it is able to access while decreasing chemical use and providing a much higher-quality water for making steam than other more conventional technologies, all while decreasing the amount of …
Is dowex a cation exchanger?
DOWEX® 50 W – cation exchangers, strongly acidic: Spherical beads, sulfonated polystyrene/ DVB matrix.
What is Dowex ion exchange resin?
DOW Ion exchange (IX) resins are polymers that are capable of exchanging ions with ions in a solution that is passed through them. DOW’s IX resins come in a variety of chemical compositions, polymer structures, and particle sizes to meet current and developing industry needs and requirements.
What is resin regeneration?
Regeneration is a process that takes ion exchange resin beads that are exhausted (fully loaded), and removes ions that have been picked up during the in-service cycle so the resin can continue to be used.
How does dowex resin work?
How does ion exchange resin work? Put simply, ion exchange is a reversible interchange of charged particles—or ions—with those of like charge. This occurs when ions present on an insoluble IX resin matrix effectively swap places with ions of a similar charge that are present in a surrounding solution.
Which type of resin is Dowex 3?
Description DOWEX™ MAC-3 Weak Acid Cation Resin has high exchange capacity, excellent regeneration efficiency, very good resistance to osmotic shock, plus good chemical and physical stability.
How does ion exchange resin regeneration?
The strong acid cation exchanger resin is regenerated with sulphuric or hydrochloric acid, which effectively strips off the calcium, magnesium and sodium from the resin, substituting hydrogen. Hydrochloric acid is typically applied at between 4 and 6%.
Can you recharge ion exchange resin?
The resin can be recharged by washing it with a solution containing a high concentration of sodium ions (e.g. it has large amounts of common salt (NaCl) dissolved in it). The calcium and magnesium ions migrate from the resin, being replaced by sodium ions from the solution until a new equilibrium is reached.
What ion is exchanged by ion exchange resin?
Ion exchange resins consists of two main types, i.e., cation exchange resins, that exchange positively charged ions, such as sodium, for calcium, and anion exchange resins, that exchange negatively charged ions, such as chloride, for arsenic.
How long do ion exchange filters last?
about 10 to 15 years
As a general rule, you can expect an ion exchange resin to last about 10 to 15 years in water treatment (as opposed to four to eight years for anion exchange resins).
What is AmberLite resin?
AmberLite™ IRC120 Na Ion Exchange Resin is a Gaussian, Gel, Strong Acid Cation Exchange Resin for Industrial Softening Applications. This durable resin offers a good balance of capacity and strength resulting in long lifetime for co-flow regenerated systems in industrial water treatment.
