- EU Municipal Wastewater Directive (EU 2024/3019) tightens phosphorus discharge limits and must be transposed into national law by mid‑2027.
- Pilot tests showed Bayoxide E IN 20 (goethite) achieved sustained effluent ≤0.1 mg/L phosphorus and is regenerable with caustic soda while requiring less rinse water and producing desorption solutions usable as fertilizer.
- Lewatit MDS TP 108 demonstrated removal of short‑ and ultra‑short‑chain PFAS at Chemours Netherlands; Lewatit TP 108 DW is approved for drinking‑water use and LewaPlus includes a PFAS Basic Design Module.
- Lewatit MDS TP 260 (Al‑loaded) kept fluoride below 1 ppm at a Chinese semiconductor plant and can cut regeneration chemical use by nearly 50% over an assumed 5‑year service life.
Regulatory context
The EU Municipal Wastewater Directive (EU 2024/3019) tightens phosphorus discharge limits and must be transposed by mid‑2027; LANXESS will present solutions at IFAT, May 4–7, 2026 (Messe München, Hall A2, Booth 344).
Phosphorus removal
Bayoxide E IN 20 (goethite) achieved sustained effluent ≤0.1 mg/L phosphorus in pilots, is regenerable with caustic soda with reduced rinse‑water demand versus iron hydroxides, produces desorption solutions usable as fertilizer, and will be validated in a larger Dutch demonstration plant.
PFAS, micropollutants and fluoride
Lewatit MDS TP 108 demonstrated removal of short‑ and ultra‑short‑chain PFAS at Chemours Netherlands; Lewatit TP 108 DW is approved for drinking‑water applications and the LewaPlus tool adds a PFAS Basic Design Module; Lewatit VP OC 1064 MD PH targets organic micropollutants and is regenerable with methanol with a pilot planned in southern Germany; Lewatit MDS TP 260 (Al‑loaded) preferentially binds fluoride, is regenerable with aluminum salts, has kept effluent <1 ppm at a Chinese semiconductor plant, and can cut regeneration chemical use by nearly 50% over an assumed five‑year service life.
Ultra‑pure water and PEM electrolysis
Lewatit UltraPure ion exchange resins aim for very low TOC release and low residual conductivity for semiconductor UPW and continuous impurity control in PEM electrolysis; related technical presentations at IFAT include sessions on PFAS, analysis and drinking‑water treatment, and a Hydrogen Stage talk on ion exchange resin properties for PEM electrolysis (May 6, 12:00).
