The shortage of clean water has become a global problem. Population growth, air pollution, and climate change will all exacerbate the situation and especially megacities will have to manage their available water carefully.
Products and processes from LANXESS are already used for water treatment worldwide, helping companies and communities alike utilize water as efficiently as possible. These products play an important role in the purification and treatment of drinking water, wastewater, and industrial process water. Crystal clear water for today’s and tomorrow’s megacities.
Intelligent solutions from the chemical industry are needed to meet the challenges associated with the megatrend of water. As one of the world’s largest and most innovative suppliers of products to remove toxic, harmful and disruptive substances from raw, process and wastewater, LANXESS plays a key role in the market. Products and solutions from LANXESS help to desalinate water, keep it free of harmful substances and bacteria for all kinds of industrial applications and produce clean water for humans and animals to drink.
Water is needed for a whole host of applications that extend far beyond our daily drinking requirements. And the demands of the various branches of industry are as diverse as they are challenging. At power plants, for example, limescale deposits need to be systematically removed, because they would significantly impair plant operation and could even damage components. The principle is the same for both large- and small-scale applications. Domestic appliances such as washing machines, dishwashers and coffee machines last longer if the water contains only small quantities of dissolved limescale.
The necessary softening is achieved, for example, using ion exchange resins from LANXESS’s Liquid Purification Technologies business unit, which are sold under the Lewatit® brand. In simplified terms, ion exchange resins are tiny beads with a diameter of between 0.3 and 1.2 millimeters that absorb positively or negatively charged particles (ions) and release other particles in exchange. Manufacturers of semiconductor products and solar panels need more than just limescale-free water, though.
They depend on ultrapure water that is free of virtually all foreign bodies. This is hardly surprising, because even a single foreign molecule could cause a short-circuit and thus an irreversible defect in components. Ion exchange resins can achieve this level of purity, too.
