BC85 is an acrylic based gel weak acid cation exchange resin containing carboxylic groups. It can be used in the cases of softening, dealkalizing, deionization and chemical processing. It is ideally suited for softening of high TDS water and for special applications such as treatment of aqueous organic solutions and selective separation of heavy metal cations. It can also be used for isolating and purification of biochemical and pharmaceutical substances. BC85 has high operating capacity for divalent cations and extremely high regeneration efficiency. This resin is supplied in the hydrogen (H) form or in the sodium (Na) form for special applications. BC85 series contents three products: BC85 for general application; BC85FC for double compartment bed and floating bed system; BC85SC for dual bed system
