Q1: What is the primary function of Zhengguang ZGC 108 EDI Resin in ultrapure water systems?
A: Zhengguang ZGC 108 EDI Resin is a mixed-bed ion exchange resin specifically engineered for use in Electrodeionization (EDI) modules. It continuously removes residual ions from reverse osmosis permeate to produce high-purity water, supporting stable operation and extended module service life under typical industrial feedwater conditions.
Q2: Is ZGC 108 compatible with standard commercial EDI units?
A: Yes, ZGC 108 is designed to meet the physical and electrochemical requirements of mainstream EDI stack configurations. Its particle size distribution, moisture content, and chemical stability allow direct replacement or retrofitting in many OEM systems—though compatibility verification with specific module designs and operating parameters is recommended prior to full-scale deployment.
Q3: How does ZGC 108 differ from conventional mixed-bed resins used in polishing tanks?
A: Unlike batch-type mixed-bed resins, ZGC 108 features optimized bead integrity and low-pressure drop characteristics for continuous current-driven regeneration in EDI stacks. It exhibits enhanced resistance to osmotic shock and fouling under dynamic flow and electrical field conditions, enabling sustained ion removal without chemical regeneration cycles.
Q4: What feedwater quality is recommended for optimal performance?
A: For reliable long-term operation, ZGC 108 performs best when fed with reverse osmosis permeate having total dissolved solids (TDS) below 10 ppm, low silica content, and minimal organic or oxidant contamination. Pretreatment to reduce hardness, iron, manganese, and chlorine residuals is strongly advised to prevent premature resin degradation or scaling.
