1. Description
Hydrolite ZGA 451 is a type of anion exchange resin containing a tertiary amine group [-N(CH3 ) 2 ] in a styrene-diethylenebenzene copolymer with a macroporous structure. It is primarily used for the production of pure and ultrapure water, and is particularly suitable for treating water resources with high salt and organic content, as well as for the treatment of chromium-containing wastewater and decolorization of sugar solutions, etc.
