PREDICTED & SAVED Worldwide. Taking action before it’s too late. “We want to act early to prevent unplanned downtime from happening in the first place,“ says Bastian Höfer, Head of Predictive Maintenance, PTSE GF. Together with his team, he is introducing a predictive maintenance program world- wide. “With the help of AI and sensors integrated into the systems, it is possible to predict – with a very high de- gree of probability – when and why a compressor, agitator, or other system component might fail,“ he explains. Bas- tian Jana, Head of Production Supporting Solutions, IT GF, highlights one particularly noteworthy aspect: “The AI not only detects obvious anomalies such as a pump vibrating. It also analyzes com- plex vibration and temperature profiles in their interaction with other process variables.“ This is how it determines wheth- er machines or systems are deviating from their normal behavior and intervention is required. Possible outages are sometimes detected weeks in advance. Since launching the global rollout of the predictive main- tenance activities, the team has already achieved savings in the seven-digit range. The goal now is to monitor not only individual machines, but entire production processes with AI assistance. THREE QUESTIONS FOR BART GOOSSENS, Regional Sales Manager, LPT BU in Belgium. Resin to the Rescue Mr. Goossens, first of all, congratu- lations on securing the contract with the Belgian company De Watergroep. This makes LPT one of the first suppliers to offer ion exchange resins for the removal of PFAS from drinking water. How did you manage that? Bart Goossens: With my charm, of course! All jokes aside, we were able to demonstrate in application tests that our resins bind more PFAS than the ion exchangers from some of our competitors. Our Lewatit® TP 108 DW, for example, is more than 20 percent better than the next best competitor. That’s a powerful argument for our customers. I had heard early on that they wanted to treat drinking water in a nature reserve near Brussels. I immedi- ately saw this as a great opportunity to show a larger customer base how well our ion exchange resins remove PFAS from drinking water. And did it go well? Absolutely. Since securing the con- tract, we’ve already received several inquiries. This is one of the first and largest drinking water projects in Europe to use ion exchange resins for PFAS removal. In this respect, it naturally makes us stand out. The drinking water industry is actually conservative. But PFAS have become a major issue in recent years.* The general assumption is that the maxi- mum permissible concentrations are going to be reduced even further. That’s why drinking water suppliers are reacting. Public organizations are also exerting their influence. The mobile systems are highly flexible and can be up and running quickly. They can already be used while a large plant is being built. Or they can be used selectively until – as in our case – other, less affected sources of drinking water can be used. In any case, these modular water treatment systems are highly impressive: one of them can process up to 190,000 liters of drinking water per hour. Do you see potential for LPT here? Absolutely. So far, we have been particularly strong in the wastewater and industrial water sectors, where we also see further opportunities for growth. Mobile units are used here as well. We now want to expand our business with our ion exchangers in the field of drinking water treatment. PFAS are found throughout Europe and the United States. Americans have been using ion exchange resins to remove PFAS for years. A great deal of research is being conducted in this area. Currently, the spent resins contaminated with PFAS are incinerat- ed at high temperatures. But research- ers are looking for more sustainable solutions. We are in close contact and are preparing to ensure that our ion exchangers can be perfectly integrated into the new technologies. That’s the next step. And we’re ready for it. *PFAS is the abbreviation for per- and polyfluoroalkyl substances: synthetic chemical compounds that have been produced on a large scale since the 1950s. PFAS can be found in fire extinguishing foams, textiles, frying pans, the paper used to wrap hamburgers, weatherproof jackets, electronics, means of transport, in the energy sector, and in medical devices. Studies sug- gest that PFAS could trigger various diseases such as elevated cholesterol levels, thyroid dysfunction and possibly cancer. In 2020, the EU introduced stricter drinking water guidelines for PFAS, and in 2023, the EU Commission presented a proposal to ban the entire group of substances. 01/2025 | Xpress 5
