ZGC258 Macroporous Weakly Acrylic Acid Cation Exchange Resin

P0BRODUCT DESCRIPTION

ZGC258 is an acrylic – based macroporous weak acid cation exchange resin containing carboxylic groups. It can be used in the cases of softening, dealkalizing, deionization and chemical processing. It is ideally suited for softening of high TDS water and for special applications such as treatment of aqueous organic solutions and selective separation of heavy metal cations. It can also be used for isolating and purification of biochemical and pharmaceutical substances.

ZGC258 has high operating capacity for divalent cations and extremely high regeneration efficiency. This resin is supplied in the hydrogen (H) form or in the sodium (Na) form for special applications. ZGC258 series contents three products: ZGC258 for general application; ZGC258FC for double compartment bed and floating bed system; ZGC258SC for dual bed system. And ZGC 258DQ is deeply treated for drinking water application.

 

FEATURES & BENEFITS
● CARBOXYLIC FUNCTIONAL GROUPS

Give extremely high regeneration efficiencies and high operating capacities.

● FINE PARTICLE SIZE, LOW PRESSURE DROP

95% of beads are in the assignation range; giving a lower pressure drop.

● SUPERIOR CHEMICAL AND PHYSICAL STABILITY

93% sphericity, combined with low swelling, macroporous structure, high crush strength, and uniform particle size provide greater resistance to bead breakage due to mechanical, thermal or osmotic stresses.

APPLICATIONS

ZGC258 in the hydrogen form can be used to remove divalent cations associated with alkalinity when operated as the primary cation unit in multiple bed demineralizers. The weak acid resin can be economically regenerated using the waste acid from the secondary cation unit.

ZGC258 is used to separate certain antibiotics from the fermentation broths in which they are produced, and also in their final purification. It can be suitable for separation and purification of the amino- acids and many kinds of biochemicals.

ZGC258 can be operated in the sodium or hydrogen cycle to remove heavy metals from waste streams with a Ph above 5.5 in the absence of hardness. Operation in the sodium form provides a neutral Ph effluent but requires a two stage regeneration.
