Seawater = drinking water

At RN Solutions we make seawater suitable for drinking water using membrane distillation technology. With our special rectangular filter units, we desalinate seawater and produce demineralized water. Demineralized water is not suitable for drinking. But you can drink it by simply adding some minerals, such as calcium and magnesium.

We have tested our new lab size Air Gap filter unit with a new PTFE membrane.

RN Solutions: Air Gap Filter (1 m2)
T max: 55° C – ∆ T 5° C – Flux 7,7 ltr/ m2/hour

At a temperature difference of 5 ° C, with a maximum temperature of 55 ° C, we received a flux of over 7,7 liters per m2 per hour! A year ago we had a flux of 3 liters per m2 per hour. A nice progress that we are very proud of. Soon we will test our full size Air Gap filter unit of 30 m2.


More to follow soon. For more information, please contact us.
