HVR’s technology is based on taming the natural phenomena of ‘water evaporation’ followed by permeation through a porous barrier

These water vapors, gather to form clouds. When cooled enough, will condense to water droplets. These droplets eventually become rain and produce freshwater filling lakes, rivers and streams.

HVR’s Technology Features

1. Recovers up to 95% and delivers Ultra-pure water even from highly polluted or contaminated water feeds.

2. The quality of the purification is >99,9%. Read about our tests results. Future ready!

3. Instant quality control of the purity /conductivity, less laboratory test needed.

4. Gentle, all in one process, high automation, low maintenance no filter replacements, 10 years longevity proven.

5. Technology mostly low grad thermal driven 50oC to 90oC. Ideal for waste heat recovery, cooling, solar thermal and renewable.

6. OFF/ON grid solution, autonomy in drinking water supplies.

7. Modular: can grow with the business

8. Possibility to valorise the highly concentrated retentates
