LANXESS Unveils Innovative Solutions for Water Treatment and Recycling at IFAT 2024

(IN BRIEF) LANXESS is set to showcase its latest advancements in water treatment and recycling technologies at IFAT 2024 in Munich, from May 13 to 17, 2024. The company will spotlight solutions for PFAS removal, battery recycling, and PEM electrolysis for hydrogen production. With a focus on sustainability and innovation, LANXESS aims to address key challenges in water management and contribute to the global transition towards greener technologies. Attendees can also participate in informative sessions and explore new product offerings, including the extended LewaPlus design software module for mixed-bed resins.

(PRESS RELEASE) COLOGNE, 30-Apr-2024 — /EuropaWire/ — Ion exchange resins from the Lewatit product family and adsorbers from the Bayoxide brand provide the basis for convincing answers to a wide range of challenges wherever water and aqueous solutions are involved. This is illustrated by the appearance of the specialty chemicals group LANXESS at this year’s IFAT. The world’s leading trade fair for water, sewage, waste and raw materials management will take place in Munich from May 13 to 17, 2024.

“Everyone is talking about climate change, the energy transition and the ongoing electrification of our everyday lives – especially in the area of mobility – and the opportunities and challenges they present. We are proud that we can make a significant contribution to solving today’s challenges with our products. An international trade fair such as IFAT, which is dedicated to these key issues of our time, is an excellent platform to present our solutions and innovative contributions and to discuss them with customers and interested parties. That’s why we’re here,” explains Michael Rockel, who has headed the Liquid Purification Technologies business unit at LANXESS since February 2024.

LANXESS will also be offering several “Lunch & Learn” sessions at IFAT between 11 a.m. and 2 p.m. on the three days of the fair, May 14, 15 and 16, which are specifically designed to promote technical dialog with customers. The program is available at www.lewatit.com. Prior registration is possible and is requested for organizational reasons.

Resins for hydrogen production and battery recycling

“Green” hydrogen, i.e. hydrogen produced using renewable energy, is becoming a cornerstone of the energy transition. Splitting water in an electrolyzer with a proton exchange membrane (PEM) produces hydrogen and oxygen with efficiencies of over 60 percent. Demineralized ultrapure water (UPW) is used. During electrolysis, traces of impurities pass into the water, which must be removed so that they do not impair the process and in particular the sensitive PEM. In a process proposed by LANXESS, partial flows of the process water and the feed water required to supplement it are therefore continuously purified. The Lewatit UltraPure resins used for this purpose were developed specifically for such tasks.

Hans-Juergen Wedemeyer’s presentation entitled “Effective Process Water Treatment for Proton Exchange Membrane (PEM) Electrolysis Installations with Lewatit Ultrapure Ion Exchange Resins” will provide detailed information on this on May 15, 2024, at 10:35 a.m. on the “Hydrogen Stage” in Hall A4 at IFAT.

Lewatit exchange resins can also be used to advantage in the recycling of lithium-ion batteries to reliably remove impurities in the ppm range, such as zinc, copper, aluminum and iron, after acid digestion of the black mass. The valuable metals nickel, cobalt, manganese and lithium can then be recovered and recycled.

No more trace of PFAS in the water

The removal of PFAS (per- and polyfluoroalkyl substances) from surface, ground and drinking water with the aid of ion exchange resins is currently the focus of attention due to the worldwide spread of environmental contamination with these fluoroorganic compounds. On May 14, 2024, at 1:30 p.m. on the “Green Stage” in Hall C4 at IFAT, Dr. Dirk Steinhilber will be presenting in detail how tailor-made resins can be used to reduce the concentration of PFAS of different chain lengths down to the detection limit in the ppt range. His presentation is entitled “The Use of Selective Lewatit Ion Exchange Resins for the Removal of Emerging Contaminants: PFAS and Beyond.”

Further Scopeblue resin for drinking water treatment

In addition to three weakly acidic acrylate-based ion exchange resins, the strongly acidic polystyrene-based cation exchange resin Lewatit S 1567 now also meets the requirements for Scopeblue products. This is primarily due to the styrene used as a monomer in the mass balance process, which is obtained from renewable or waste-based raw materials, namely tall oil fatty acids. In this way, it is possible – compared to conventionally produced resin – to substitute more than 90 percent of fossil raw materials and reduce the carbon footprint by up to 76 percent. The resin is produced at the Bitterfeld site in Saxony-Anhalt, which, like Leverkusen, has recently been certified in accordance with the ISCC PLUS standard (International Sustainability & Carbon Certification). The same applies to the method used for mass balancing.

The Scopeblue sustainability umbrella brand identifies LANXESS products of which more than 50 percent is based on renewable raw materials or whose carbon footprint is less than half that of the corresponding product made from conventional raw materials. “This allows our customers to act in a more sustainable way,” emphasizes Dr. Stefan Neufeind, Head of Technical Marketing in the Liquid Purification Technologies business unit at LANXESS.

The monodisperse Lewatit S 1567 can be used in cartridges as well as in large-scale drinking water treatment and is characterized by favorable kinetics and high operating capacity. It is chemically and mechanically very stable and can be disinfected very effectively.

Design software LewaPlus extended once again

The functional scope of the free-to-use LewaPlus design software has grown continuously over the years and covers all important areas of application for Lewatit ion exchange resins, from large power plants to drinking water and wastewater treatment and applications in the food industry.

A new addition is a module for simulating ready-to-use mixed beds. It allows precise hydraulic design and calculations depending on the feed and required product water quality. Ready-to-use mixed beds are used in industry for the production of everything from demineralized to ultrapure water.
