Versatile and high-performance ion exchange resins from the Lewatit product range and adsorbers under the Bayoxide brand for a diverse range of applications will once again be at the heart of the portfolio showcased at
The international trade show for the process water, drinking water and wastewater industries will take place in
‘When it comes to choosing the right ion exchange processes, numerous different aspects play a role. Sustainability is increasingly becoming a key criterion, and we are responding by developing resins based on sustainably produced raw materials,’ says Dr. Stefan Neufeind, head of Technical Marketing for the Liquid Purification Technologies business unit at LANXESS. ‘Our LewaPlus design software is a valuable tool that allows the potential of our resins to be leveraged as effectively as possible. It covers all the relevant steps, from choosing the resins and processes and dimensioning plants through to calculating investment and operating costs and optimizing processes.’
Greater sustainability thanks to Scopeblue and Eco resins
Resins that LANXESS markets under the Scopeblue umbrella brand offer significantly enhanced sustainability. This umbrella brand is used for products that have a renewable raw material content of more than 50 percent or a

The three weak acidic cation (WAC) exchange resins Lewatit S 8227, Lewatit S 8229 and Lewatit CNP P even meet both Scopeblue conditions. More than half of the dry mass of these acrylic resins originates from acrylonitrile, which can be obtained from tall oil in accordance with the mass balance approach. The
An important area of application for these WAC resins is cartridges for water filters, which can be used for producing partially softened water in the preparation of, for example, hot drinks such as coffee and tea. Filter systems like these are used both in the home and commercially.
According to internal LANXESS estimates, the ion exchange resin accounts for the largest share of these cartridges in terms of mass and volume, along with the plastic housing and the activated
Although Eco-brand resins do not yet fulfill the strict criteria under the Scopeblue definition, they also have a much reduced

LewaPlus – calculate, model, simulate, optimize
For decades now, LANXESS has been offering its customers the free design software LewaPlus, which is comprehensively deployed by experts within the company, too. The functional scope of the software has grown continuously over the years, and today it can be used for not only simple design tasks but also complex simulations and cost calculations.
The software package now features numerous modules that enable the combined configuration of ion exchange, reverse osmosis and ultrafiltration stages. A whole range of applications are covered here – from power plants and industrial water-steam circuits through to drinking water treatment, wastewater treatment and food industry processes. LewaPlus allows both the loading and the regeneration phase to be reliably modeled and adapted in line with customer-specific requirements and circumstances. In this way, new plants can be planned and the performance of existing installations checked and, if necessary, optimized.

The software is now available in eleven languages and is extremely user-friendly. Technology modules can be dragged, dropped and combined to create complex system configurations. LewaPlus is currently being used by more than 6,000 users in more than 100 countries. Customers can store their results in PDF files for ease of documentation and sharing with LANXESS experts, for example for further analysis or consultation purposes.
