Industries requiring ultra-pure water for boilers, pharmaceuticals, power generation and electronics cannot tolerate dissolved salts or minerals in feedwater. Resin-based demineralization (DM) systems provide a proven solution for producing high-quality deionized water through ion exchange technology. In this process, cation exchange resins replace positively charged ions (Ca²⁺, Mg²⁺, Na⁺) with H⁺, while anion exchange resins replace negatively charged ions (Cl⁻, SO₄²⁻, NO₃⁻) with OH⁻, which then combine to form pure H₂O.
WOG Technologies Limited designs and delivers resin-based DM plants that ensure consistent water purity, low conductivity and minimal silica levels for critical process applications. Our solutions are engineered for both greenfield and retrofit installations and support zero liquid discharge (ZLD) and reuse strategies.
Resin-based DM plants use cation and anion exchange resins to remove dissolved salts and produce demineralized water:
Contact WOG Technologies Limited to design a resin-based DM plant that ensures consistent water quality and operational reliability for your industry.
Resin-based DM plants remove ions entirely through ion exchange and achieve ultra-low conductivity, while RO reduces dissolved solids but may require polishing for critical applications.
Regeneration frequency depends on feedwater quality and plant loading but typically ranges from several days to a few weeks for continuous operation.
Yes. Pretreatment, such as softening or filtration, can be added to stabilize feedwater and optimize resin life.
Yes. Our systems are designed to comply with USP, EP and ASTM standards for pharmaceutical and biotech water.
Absolutely. We integrate DM with membrane systems to provide hybrid solutions for higher efficiency and lower chemical usage.
