Recommended Areas of Application

Ultrafiltration is the ideal choice for a whole host of applications:

- Purification of surface water, groundwater and spring water to make drinking water
  and process water
- Treatment of waste water
- Pretreatment in sea water desalination plants in combination with reverse osmosis
  or thermal treatment
- Water for industrial use to close water cycles

Saying Goodbye to Sand Filtration
Sand filtration was considered to be a state-of-the-art method in the world of water treatment for many hundreds of years. Similar to the natural water cycle, in which water flows through layers of rock and sand, this method involves trickling the water through beds of sand in order to clean it. It was truly a revolution of its time in newly developing cities and continues to be the principal method used in many communities. But genuinely revolutionary technology nowadays goes under a different name: ultrafiltration with nanoscale membranes.

There are now numerous applications where ultrafiltration can replace or effectively supplement sand filtration. It achieves better results in filtering out pathogens, takes up significantly less space and is renowned for being easy to manage and simple to integrate in complex water treatment systems as either an upstream or downstream stage. But its biggest advantage is the fact that, regardless of the degree of contamination of the original water, the filtered water always maintains the same superb level of quality and purity. Sand filtration simply cannot match this process. Heavy rainfall, floods or contamination in the water supply can mean that the sand is no longer capable of retaining all the dirt particles. In contrast, ultrafiltration is not dependent on outside influences, which allows it to provide a consistent supply of top-quality water.
