WA20 and WA21J do not have any neutral salt splitting capacity. They have high total exchange capacity and high regeneration efficiency. The porous styrene polymer imports high chemical stability, high mechanical strength against attrition loss, high thermal stability and high durability against organic fouling.
These resins are used for the removal of strong mineral acids in standard water treatment applications. Theycan also be applied in special process separations such as the treatment of organic solvents.
It should be noted that WA21J has a high porous structure and provides excellent mechanical strength for more rigorous industrial applications.
WA30 resin is a weak base anion exchange resin based on high porous, styrene/ DVB polymer matrix. WA30 has tertiary amine functionality with high regeneration efficiency. The high porous styrenic matrix imparts excellent chemical stability, excellent mechanical and osmotic strength (to minimize attrition), high thermal stability and excellent durability against organic fouling. The high porous matrix of WA30 provides a high reaction rate.
WA30 is the bench mark which all macroporous weak base anion exchange resins are compared with. WA30 is used for very wide variety of applications, such as 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.
