ZGD 750 Macroporous strongly basic anionic ion exchange resin

Description

PRODUCT DESCRIPTION ZGD 750

ZGD 750 (Cl or OH form) is a high-capacity, organic-fouling-resistant, macroporous, type I, strong-base anion exchange resin. Available in chloride and hydroxide forms, ZGD 750 is primarily used for the removal of organic compounds and color from water/wastewater and the sugar industry.

ZGD 750 is highly recommended for use upstream of anionic demineralizers or mixed demineralizers where organic matter removal is required to protect resins from fouling.

ZGD 750 can also be used to remove certain heavy metals in water or wastewater where contamination resistance and thermal or chemical stability are required.
