Ion Exchange Resin

Ion Exchange Resin

Lewatit 80 is a high quality, high capacity strongly acidic, gel-type cation exchange resin of a uniform bead size with a styrene-divinylbenzene copolymer. Its high total capacity, very good chemical and mechanical stability make it especially suitable for use in softening of industrial water as well as all conventional ion exchange process.
Lewatit 80 resin is supplied in a sodium form as colored translucent beads in one cubic foot bags and larger bulk bags. The resin does not contain chlorinated solvents. and the manufacturing process ensures low taste, odor and color throw for potable water applications. The resin meets the requirements for paragraph 173.25 of the Food Additive Regulation of the U.S. Food and Drug Administration. When used in softening applications,Lewatit 80 resin has 30,000 grains of exchange capacity when regenerated with 15 pounds of NaCl per cubic foot and 20,000 grains with six pounds NaCl per cubic foot ensure high salt usage efficiency and low operating cost.

  • No chlorinated solvents are used during manufacturing
  • Manufacturing process insures low taste, odor and color throw for portable waters
  • Strong and durable beads ensure long service life
