Ion Exchange Resin for Organics Removal

Lanlang^® TA301D is a premium grade macroporous weak base anion exchange resin with polystyrene matrix and tertiary amine (Dimethylamine) function group in standard Gaussian size distribution. Its macroporous structure makes it can adsorb soluble organic molecules and can resist to osmotic & mechanical shock and oxidation. The weak base functionality makes TA301D could be regenerated easily even using waste caustic left from regeneration of strong base anion resin. So TA301D could be used multi bed demineralizers to prolong the lifetime of strong based anion resin and prevent it from organic fouling.

Naturally occurring dissolved organics collectively measured as TOC (Total Organic Carbon), COD (Chemical Oxygen Demand) or BOD (Biological Oxygen Demand) can foul and affect the performance of ion exchange demineralization plants. This kind of problem is normally associated with plants that treat surface waters which contain either naturally occurring or synthetic organics. Manmade organic material normally enters the supply via drains as the rivers pass through towns or industrial areas. In all cases these organic fouling materials have a large molecular weight and are usually hydrophobic in nature. The naturally occurring organics are often referred to generally as Humates and Fulvates.These large, complex organic molecules are attracted and captured on ion exchange resins, resulting in irreversible fouling, particularly of strong base anion resins.
