Ultrafiltration

The most efficient technology for drinking water purification

Ultrafiltration is a technology that can turn unusable water into safe drinking water. With significantly better performance and cost efficiency than any other method, it can remove both sediments and pathogens (bacteria, viruses, parasites) from water in a single step.

Desinfection performance in figures

The filtering of more than 99.99 per cent of all pathogens has been proven in extensive tests, demonstrating that drinking water is completely free of bacteria after filtration. No further disinfection is required.

The use of ultrafiltration is recommended by many health authorities in Germany, since it offers clear advantages over other methods used for purifying drinking water:
Desinfection of the drinking water with chlorine, for example, a common practice, is not possible with many spring and well waters due to the carcinogenic by-products that can be generated. Pathogens such as parasites and spores are also often chlorine-resistant. UV irradiation is also often used for disinfection. In this case, there must be absolutely no cloudiness of the original water, so that at least bacterial pathogens can be effectively destroyed by the UV radiation. With brackish and superficial sources especially, this is an almost irresolvable undertaking. The required removal of the sediment can only be performed using the ultra-filtration method, which simultaneously removes more than 99.99% of all germs from the water.

A further plus point for ultrafiltration is its compatibility with other methods used for purifying drinking water. The use of activated carbon before ultrafiltration removes pesticides and drug residues, and with downstream nanofiltration, the water can be softened. Reverse osmosis will desalinate the water after ultrafiltration.
