This is a kind of phenolic weakly alkaline anion exchange resin which has macroporous structure. It has large exchange capacity, strong resistance to permeation, good exchange and adsorption capability, and excellent elution and regeneration properties.

P313 is a high capacity, shock resistant ,acrylic gel ,weakly base anion resin. Supplied in the free bass form as moist, tough, uniform spherical beads. S313has tremendous regeneration efficiency and low rinse requirement and is also capable of reversibly adsorbing large organic ions.P313is intended primarily for use in multiple bed deionization ,pharmaceutical , and food grade process applications.

S830 is a high capacity macroporous anion exchange resin with an acrylic matrix. This matrix ensures excellent and fast removal of both mineral and organic acids. The efficient desorbtion which occurs upon regeneration markedly reduces the risk of resin fouling, thus maintaining the exceptionally high operating capacity which exists as a result of the complex amine functionality. S830 is ideally suited to the removal of nitrates or sulphates from process waste and from condensate in nitrogen based fertilizer production. It is regenerated very efficiently with ammonia.
