FDA-compliant and certified to meet NSF/ANSI Standard 61 for potable water and food-contact applications.
Highly uniform spherical beads ensure consistent hydraulic performance and low pressure drop in service.
Exceptional chemical stability in repeated regeneration cycles with sodium chloride brine.
Low extractables profile, minimizing leachables such as total organic carbon (TOC) and heavy metals.
Optimized crosslinking (8% DVB) balances swelling control, mechanical strength, and ion exchange capacity.
Beverage production — softening process water for carbonated drinks, juices, and dairy-based beverages.
Food processing — pretreatment of boiler feedwater and rinsing water in canned goods and ready-to-eat facilities.
Pharmaceutical water systems — primary softening stage for purified water (PW) and water-for-injection (WFI) pretreatment.
Commercial kitchen and institutional foodservice — scale prevention in steam cookers, dishwashers, and ice machines.
Organic-certified food manufacturing — approved for use where non-GMO and food-grade material compliance is required.

Q1: What does “Food Grade” mean for this softening resin?
A: “Food Grade” indicates that Zhengguang ZGC 108 DQ is manufactured under strict quality control conditions suitable for indirect food contact applications, such as water treatment in beverage production or ingredient processing systems. It complies with general food safety principles for ion exchange resins, including low extractables and absence of heavy metals or toxic monomers.
Q2: Is ZGC 108 DQ compatible with common industrial softening equipment?
A: Yes — ZGC 108 DQ is a standard gel-type cation exchange resin with uniform spherical beads and high physical stability, designed for use in fixed-bed softeners, automatic regeneration units, and modular water treatment skids commonly found in food & beverage, dairy, and bottled water facilities.
Q3: How does ZGC 108 DQ differ from standard industrial softening resins?
A: Unlike general-purpose resins, ZGC 108 DQ undergoes additional purification and rigorous testing to ensure compliance with food-grade requirements — including reduced residual crosslinkers, enhanced rinse efficiency, and documentation supporting its suitability for sensitive process water applications where product purity is critical.
Q4: Can ZGC 108 DQ be used in hot process water systems?
A: It is suitable for continuous operation at temperatures up to 120°C, making it appropriate for steam condensate polishing and hot process water softening in food manufacturing environments, provided system pH remains within the recommended range of 1–12.
