Ultrafiltration helps provide cities with clean water

GREIFENBERG, Germany, Mar. 10, 2011 -- The theme for this year's World Water Day on March 22 is "Water for Cities: Responding to the Urban Challenge." At present, some 3.3 billion people -- around half the world's population -- live in cities. And the urban population is growing by two people every second. As the number of city-dwellers increases, so too does the need for clean water. Yet the steady industrialization of countries in Asia and elsewhere is leading to more and more pollution and water shortages in the world's megacities.

The average household water consumption in industrialized countries is between 100 and 500 liters a day. But with fresh water making up just three percent of the water on Earth, cities have little choice but to pursue the goals of minimizing water usage, increasing their use of sea water and, above all, fully exploiting the benefits of water recycling.

Ultrafiltration replaces sand filters and UV irradiation
The technology required to achieve these goals is changing: Traditional methods of water treatment such as sand filtration and UV irradiation require considerable time and space and cannot cope with significant fluctuations in water quality. Ultrafiltration is therefore gradually taking over as the technology of choice. By passing dirty water through fine membranes, ultrafiltration systems remove the suspended solids, viruses and bacteria that are simply too large to fit through the ultrafine pores. The process offers numerous benefits: It does not require the use of chemicals, and the filtrate it produces is of consistently high quality regardless of the level of contamination of the source water.

German company ranked as global technology leader
Based in the town of Greifenberg on the Ammersee lake in Germany, inge watertechnologies AG is one of the world's leading ultrafiltration companies. With a global reach enhanced by its network of partners, the company has carried out numerous reference projects around the globe with its cutting-edge technology. Its range of products includes highly-efficient ultrafiltration modules and cost-effective, space-saving rack designs as the core components of water treatment plants. All the company's products are based on the in-house development of its patented membrane technology. Bruno Steis, CEO of inge watertechnologies AG, says: "Our technology offers significant advantages over conventional water treatment methods, including rapid, simple and space-saving module installation and stable, highly resilient membranes. This makes planning a water treatment facility much simpler and facilitates low-cost installation and reliable operation."

So it is hardly surprising that cities and municipal authorities from all corners of the globe are flocking to inge watertechnologies AG: German ultrafiltration technology is now up and running in Trier, Luxembourg, Sur City (Oman) and Peking. Steis adds: "Clearly, no single technology can solve all the water problems that cities face -- but we are delighted that our products can at the very least contribute towards making water treatment safer and more efficient."
