WA30 is the benchmark in which all macroporous weak base anion exchange resins are compared. WA30 is used for a very wide variety of applications, such as the removal of organic substances of high molecular weight, pretreatment of raw waters containing organic foulants, deionization, and decolorization of starch hydrolysates (such as corn syrup, dextrose, HFC’s and sugar solutions) and purification of glycerine and enzymes.
