This high level of per capita consumption can become a problem in particular for regions where potable water in itself is scarce. Such regions include the Arabian Peninsula, North Africa, and parts of the United States and Australia. Aside from the population, in most cases agriculture and other industries are ultimately dependent on the supply of water. An energy-efficient solution for safeguarding the water supply is seawater desalination through reverse osmosis. Lewabrane® membrane elements from LANXESS have proved effective in this regard. Thanks to them, it is possible to desalinate seawater either centrally for an entire region or for smaller units, such as hotel facilities.
“Water is a scarce resource in many areas on Earth, even though 72 percent of the planet’s surface is covered by water,” says Jean-Marc Vesselle, Head of the Liquid Purification Technologies Business Unit. The reason for this is that approximately 97 percent of that is seawater and not even one percent is potable water. “That is where we come in with our products, because they help to desalinate water and other liquids, as well as remove other undesirable substances.”
