Purolite general purpose mixed bed products will provide excellent results for industrial applications such as:
- Mixed bed polisher after demineralization system
- Electrical discharge machining (EDM)
- Partial demineralization with acrylic weak base anion
- Condensate polishing
- Mixed bed polisher after reverse osmosis (RO)
- Cartridges
Specialty applications for mixed bed ion exchange resins include:
Ultrapure Water & Nuclear Power
Ultrapure water mixed bed resins are used to achieve the ultimate ultrapure water quality for the electronics industry. This proccess requires a pretreatment stage followed by what is sometimes referred to as primary treatment that comprises Reverse Osmosis (RO) or Ion Exchange (IE) Make-Up water plants, or more often, a combination of both to achieve a resistivity of 12 – 17 MΩ·cm. To achieve the ultrapure water quality, i.e. resistivity > 18.2 MΩ·cm, a final polishing stage, comprising a recirculation loop and a point of use treatment using special UPW resin grades, is required.
