Features Of Zhengguang ZGA 307 EDI Resin

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

  2. Optimized anion/cation exchange capacity ratio for balanced ion removal and extended operational cycle life.

  3. Low soluble organic extractables (SOE) meeting stringent semiconductor-grade ultrapure water requirements.

  4. Excellent chemical stability in continuous electrochemical regeneration environments, resistant to oxidation and hydrolysis.

  5. Pre-packed and pre-conditioned for direct use—minimizes system startup time and reduces commissioning risk.

Typical Applications Of Zhengguang ZGA 307 EDI Resin

  1. Ultrapure water production for semiconductor manufacturing facilities.

  2. Pharmaceutical-grade water systems compliant with USP <841> and EP 2.6.1 standards.

  3. Power plant boiler feedwater polishing in combined RO-EDI configurations.

  4. Research laboratory water purification systems requiring >18.2 MΩ·cm resistivity.

  5. Electronics manufacturing process rinse water recycling and reuse circuits.
