Company profile

For many, many years IWT GmbH has experience on water purification and the filtering of water. From the very beginning up to the market introduction, various reputable scientists have been participating in the research and development of the patented IWT-Technology.

At this very moment there is a great shortage of usable fresh water, and the available quantity of fresh water from natural sources are diminishing rapidly. In order to fulfill the worldwide demands for clean water, in future more new water purification technologies have to be developed and used to desalinate seawater into fresh drinking water or to purify contaminated industrial waste water. In the years to come, those having control over the limited quantity of available freshwater might have great economical advantages and increasing political power. In the near future the market for water purification technologies will be insatiable and the willingness to use new innovative technologies will expand.

At the Eureka World Innovation Fair in Brussels, when the IWT-Technology was presented for the first time, the technology was honoured with the Gold Medal for its trend-setting and innovative technology to purify contaminated water. After years of further developing and intensive testing, the IWT-Technology now can be introduced in the market and change the lives of millions of people world wide.

The IWT-Technology is a unique technology forsewage, fresh water, exploitation of hydrogen as well as desalination of seawater or brackish water into drinking water. It comprises of 4 techniques for the treatment of fresh/sea water/sewage as well as an innovative technology of membranes which can be operated in existing plants.


  • SP - Purification of industrial waste water
  • SD - Purification and desalination of seawater and brackish water
  • AMF - Adjustable membrane filtration
  • H2- Hydrogen Extraction
  • FWT – Fresh Water Extraction

Because of these new Technologies the IWT-systems have unique advantages in comparison to the commonly used SWRO installations. Besides a lower energy consumption, the operational expenses are significantly lower, the installations are more hours per year available and last but not least, it is possible to generate pure hydrogen. aus.
