LANXESS Confirms Over 99.9% PFAS Removal from Industrial Wastewater in Demonstration Test Using Selective Ion Exchange Resin
LANXESS has successfully demonstrated that its selective ion exchange resin, Lewatit MDS TP 108, removes over 99.9% of PFAS from industrial wastewater. The performance proves effective for the treatment of short-chain and ultra-short-chain PFAS, which are traditionally difficult to remove.

German specialty chemicals company LANXESS provides solutions for removing PFAS—including short-chain and ultra-short-chain per- and polyfluoroalkyl substances—from contaminated water using its selective resin, Lewatit® MDS TP 108. In a demonstration test conducted at Chemours Netherlands B.V. in Dordrecht, the Netherlands, it was confirmed that this resin could remove over 99.9% of all organic fluorine compounds from industrial wastewater at an industrial scale.
Short-chain and ultra-short-chain PFAS (carbon chain length 2-7) have low adsorption properties to activated carbon and are difficult for many conventional ion exchange resins to bind. In 2024, LANXESS developed Lewatit MDS TP 108, which has a bead diameter approximately one-third that of conventional resins. This allows for improved ion exchange capacity, longer service life, and maintained performance under high flow conditions.
Chemours employs a three-stage purification process: reverse osmosis, activated carbon filtration, and the use of Lewatit MDS TP 108. The system uses a three-column series configuration (one primary and two polishing filters) to remove short-chain PFAS. The plant has been in steady operation since mid-2025, meeting strict regulatory requirements and reducing emissions.

FAQ
ランクセスの「レバチット MDS TP 108」とはどのような製品ですか？
PFAS除去を目的として2024年に開発された、均一小粒径の選択性イオン交換樹脂です。従来の樹脂と比較して直径が約3分の1と小さく、高いイオン交換容量と速い交換速度を持つため、高流速条件下でも短鎖・超短鎖PFASを安定して除去可能です。
ケマーズでの実証試験の結果はどのようなものでしたか？
オランダのケマーズ・ネザーランズB.V.における工場規模の実証試験において、製造工程から発生する廃水に含まれるすべての有機フッ素化合物（PFAS）を99.9%超除去できることが確認されました。
どのような浄化プロセスでPFASを除去しているのですか？
3段階のプロセスを採用しています。1段階目は逆浸透による濃縮、2段階目は活性炭フィルターによる長鎖PFASの除去、3段階目は「レバチット MDS TP 108」による炭素数2および3の短鎖PFASの最終除去です。
使用済みの樹脂はどのように処理されますか？
汚染物質を吸着した樹脂は、使用後に高温で焼却処理されることでPFASを分解します。
本技術の運用状況はどうなっていますか？
エンジニアリングパートナーであるLogisticon Water Treatment社の設計により構築された水処理プラントが、ケマーズにおいて2025年半ばから定常運転されています。
