What is DOWEX resin used for?

Dowex Resin can be used in the following water treatment systems: Softening, to soften the feed water to meet requirements for boiler feed water e.g. Prodcution of Demiwater, Ultra pure water or deminerialized water. Ion-specific treatment.

What does dowex 50WX4 do?

Dowex 50WX4–100: An Efficient Catalyst for the Tetrahydropyranylation of Alcohols. The ion-exchange resin Dowex 50WX4–100 has been found to catalyze efficiently the protection reaction of a variety of alcohols with 2,3-dihydro-4H pyran (DHP) and dichloromethane at ambient conditions.

What is dowex?

DOWEX fine mesh resins are produced by selectively controlling the suspension polymerization technology we use to produce our standard 16 – 50 mesh industrial resins. The resulting resins consist of whole, spherical beads that provide excellent kinetic and packing properties in chromatographic separations…

What is ion exchange filtration?

The ion exchange filtration is one of the most common water filtration methods. Ion exchange process percolates water through bead-like spherical resin materials (ion-exchange resins). Ions in the water are exchanged for other ions fixed to the beads.

How do you clean dowex resin?

Hydrogen peroxide can be applied as a solution of 0.2% with a contact time of 15 minutes; 0.05% for 2 hours or 0.05% for 24 hours (0.5 BV minimum). This should be followed by a rinse to eliminate peroxide (detectable by paper re-agents) and then by a double regeneration.

What are dowex beads?

DOWEX* DR-2030 catalyst is styrenic plastic bead, functionalized with sulfonic acid groups. These tough plastic beads are insoluble in organic solvents, strong acids or base. The high level of functionality of the beads results in an acid concentration of >2M.

Is it safe to drink ion exchange water?

Though the process of ion exchange does change the nature of your home’s tap water, it doesn’t necessarily impact how safe it is to drink in normal amounts. Read on to learn more about how water softening works; what’s actually in your softened water; and why it poses virtually no risk to your health.

How long do ion exchange filters last?

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).
