Features Of Zhengguang ZGC 650 EDI Resin

  1. Highly uniform spherical bead morphology ensures stable hydraulic performance and low pressure drop in EDI modules.

  2. Optimized ion exchange capacity balance between cation and anion resins for efficient continuous deionization.

  3. Excellent chemical and osmotic stability under long-term operation in high-purity water systems.

  4. Low organic extractables and minimal TOC leaching, meeting stringent requirements for pharmaceutical and microelectronics ultrapure water.

  5. Pre-mixed and pre-conditioned in optimal volume ratio (1:1 ±0.05), ready for direct loading into standard EDI stacks.

Typical Applications Of Zhengguang ZGC 650 EDI Resin

  1. Ultrapure water production for semiconductor wafer cleaning and photolithography processes.

  2. Pharmaceutical-grade purified water (PW) and water for injection (WFI) polishing systems.

  3. Power plant boiler feedwater treatment requiring >18.0 MΩ·cm resistivity.

  4. Laboratory and analytical instrument feedwater systems demanding consistent low silica and sodium breakthrough.

  5. Food & beverage high-purity process water polishing where microbial and ionic stability are critical.
