Last month, this firm launched a new generation of gel-type, cation-exchange resins for industrial water treatment. Lewatit MonoPlus S 108 and S 108 H have optimized leaching behavior, which is an important quality characteristic regarding the effectiveness and commercial efficiency of an ion-exchange unit; the lower the resin’s tendency for self-leaching, the less total organic carbon (TOC) is released, says the firm. This release of organic substances is undesirable because it can lead to blocking of the anion exchanger. The new resin beads also remain in excellent condition after many operating cycles. Even with short cycle times, the special monodisperse ion-exchange matrix ensures long service life. — Lanxess AG, Leverkusen, Germany
