ZGA455FD-H18 Weakly basic anion exchange resin with high capacity.

Description

1. Description:Hydrolite ZGA455FD-H18 is a macroporous styrene-based weak base anion resin developed by ZG for the food industry. Compared to other weak base anion resins, ZGA455FD-H18 has a high capacity and fast exchange rate, making it ideal for adsorbing organic compounds and removing strong acidic anions in water and water-soluble solutions. Under the same conditions, water and regenerant costs are lower.

ZGA455FD-H18 has a larger pore size and specific surface area, enabling it to adsorb a large number of macromolecular organic compounds. Adsorption rates can reach 80-95%, and elution capacity exceeds 95%, making it ideal for starch desalination and decolorization.

ZGA455FD-H18 has a small number of strong basic groups and does not absorb small molecules during operation. It exhibits high mechanical strength, high storage capacity, and low swelling, making it ideal for use in juices, beverages, drinking water, and food processing, including starch, beer, sorbitol, xylitol, amino acids, and lactic acid, among other applications, to improve the flavor and clarity of products.

Note: When starting the backwash, the flow rate should be slow. Once all the resins have become flexible, gradually increase the backwash speed. Once the resins are fully activated, stabilize the flow rate until the feed water is clear.
