Remove PFAS from water with this ion-exchange resin
MonoPlus TP 109 (photo) is a new macroporous anion-exchange resin for the selective removal of contaminants, such as per- and polyfluoroalkyl substances (PFAS) from water. Lewatit MonoPlus TP 109 is especially suitable for the purification and remediation of water with PFAS concentrations exceeding 10 parts per billion (ppb). In addition to its high selectivity, the macroporous resin exhibits good kinetics and high fouling resistance, the company says. The uniform bead size ensures improved hydraulics, and the resin can be regenerated with chemicals, such as methanol and sodium chloride. Lewatit MonoPlus TP 109 efficiently binds not only different PFAS, but also complex anions, such as nitrate, bromate, chlorate and perchlorate. It can even remove chlorate from concentrated sodium hydroxide. — Lanxess AG, Cologne, Germany
