1. City wastewater recycling
Can city wastewater be reused for daily water demands? No problem with Lewabrane® reverse osmosis technology from LANXESS. How does it work? Semi-permeable membranes ensure contaminants like iron and manganese are filtered out of the water. Technologies like these are especially important in areas with a dry climate or with limited access to clean water.
2. Water treatment in industries
Making river water suitable for use in production is also possible with LANXESS technologies. We find one example in Pančevo, Serbia. Around 400 Lewabrane® membranes treat brackish water from the Danube for a refinery. Drawn around 15 km from Belgrade on the mouth of the Timiș River, the water is pre-treated in a water treatment plant, then treated in three reverse osmosis stage, each with 132 membrane elements. This provides 300 cubic meters of filtered Danube water per hour that the refinery can use for production.
3. Seawater desalination on land and at sea
Transforming seawater into drinking water? In dry costal regions where drinking water is scarce, it is one way of accessing extractable water. One example: Lazorde Bay, located west of Alexandria, Egypt. Here, a water treatment system with 48 Lewabrane® membrane elements from LANXESS converts water from the Mediterranean Sea into water of potable quality. The space-saving technology can even be used at high sea, for instance for water treatment on cruise ships.
