Lanlang ® TA204U Is a premium grade gel type I strong base anion exchange resin with standard crosslinked polystyrene matrix, quaternary amine (Trimethylamine) function group and uniform particle size. Its clear gel structure make it has excellent regeneration efficiency (both in co-current and counter-current systems) and rinse performance. TA204U in chloride form could remove both strong and weak acid radicals such as sulfate, nitrate, arsenate, chromate and silicate to extreme low concentration level. Combining with strong acid cation exchange resin (in hydrogen form), TA204U in hydroxide form can be used in all types of demineralization system including condensate polishing. TA204U is intended for reducing pressure loss and preventing system from plugging.
