P830 Macroporous Acrylic acid series weakly alkaline anion exchange resin
详细说明
1. Description
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.
