DOWEX™ Ion Exchanger Resins
We are proud to be the official distributor of DOWEX™ Ion Exchanger resins.
DOWEX™ ion exchange resins are products of Dow Water & Process Solution,
a globally recognized leader in separation technologies and solutions for industrial,
municipal, commercial and consumer water applications, as well as a variety of special separations.
The line of DOWEX™ resins includes DOWEX™ MONOSPHERE and DOWEX™ MARATHON resins that deliver significant
performance advantages over conventional resins with normal or Gaussian particle size distribution.
DOWEX™ UPS resins offer premium performance when used in either multiple-bed or mixed bed demineralisation,
as well as in such demanding applications as boiler condensate polishing of rinse water used in semiconductor
processing, radioactive waste treatment in nuclear power plant operations, and other applications with critical
water purity standards.
The advantages of uniform particle size (UPS) over conventional resins has been demonstrated
both in the laboratory and on working plants.
Their properties provide users with many additional benefits over conventional exchange resins:
- Faster kinetics
- Shorter rinse time
- Better regeneration
- Higher capacity
- Easy bed expansion
- Less resin loss
- Better separation mixed beds
- Longer resin life

Advantages of DOW UPS (uniform particle size):
- Better performance in capacity, excellent regeneration results.
- Wide range (Assortment particle size, Gel resins) and only complete product line for macroporous UPS resins.
- Highly efficient in combination with UPCORE counter current regeneration.
A fine-tuned range of DOWEX™ ion exchangers are available for a variaty of applications such as
- Domestic and industrial water softening
- Demineralisation
- Condensate polishing
- Nuclear application
- Ultrapure water for electronic industry
- Sugar treatment and many others
In addition, there are DOWEX™ resins available for specialized applications.
For example, DOWEX™ GUARDIAN resins meet the stringent iron removal and TOC cleanliness
requirements of deep bed condensate polishing in boiling water reactor (BWR) nuclear power plants.
The UPCORE System (Upflow Counter Regeneration System) is an advanced system for more productive
and more cost-effective ion exchange demineralisation.
Key advantages:
- Simple vessel design
- Easy to control and automate
- Lower operating costs
- Ideal for upgrades
- Easy configurability for layered beds
- Optimized vessel volume utilization
- Insensitive to flow rate variations
- Self-cleaning, no separate backwash step needed.
