Yuhui A-AMT is a premium grade macroporous weak base anion (WBA) exchange resin based on acrylic-divinylbenzene (DVB) copolymers with tertiary amine (Dimethylamine) functional group and standard Gaussian particle size distribution. Due to its special polyacrylic matrix structure, A-AMT has excellent efficiency on adsorption and desorption of natural organic substances. Due to the special functional group,A-AMT has excellent regeneration efficiency. Its macroporous matrix structure offers the optimal performance on resistance to both osmosis shock and organic fouling. A-AMT is developed to be used for industrial water demineralization with high organics content as the pretreatment before SBA bed.
