BD201 is a macroporous strong-base Type I anion exchange resin based on polystyrene with quaternary amine groups. It has a unique macroporous structure which contributes its high capacity and excellent physical and chemical stability. Its resistance to organic fouling is superior to gel resin
because of its large pore structure. The resin is mainly used in preparation of pure water, ultra pure water and condensation polishing. It can be used for waste water treatment, recovery of metals and many chemical processing applications.
