LEWATIT® A 365

Lewatit® A-365 is a food grade, macroporous, weakly basic anion exchange resin based on a crosslinked polyacrylate.

Lewatit® A-365 is designed to offer exceptional high operating capacity, good physical stability and excellent resistance to mechanical osmotic shock. The acrylic matrix of Lewatit® A-365 offers rapid kinetics for common anions, including larger, more bulky, anions like sulfate.

Lewatit® A-365 is fully regenerable with NaOH and other weak bases. As Lewatit® A-365 is a true weak base resin, the regenerant consumption is close to stoichiometric. Lewatit® A-365 is recommended for applications including demineralisation of high TDS waters, selective sulfate removal, purification of aqueous solutions, including decolorisation applications and once-through cartridge applications.

Lewatit® A-365 is supplied in a heterodispersed particle size distribution as spherical beads in the fully swollen moist free base form. Lewatit® A-365 is prepared with a minimum amount of fines (-50 mesh particles) resulting in low pressure losses during service.
