• Welcome

    Aqua|still was founded in 2008 after a period of eleven years of R&D and is now one of the few companies in the world who apply membrane distillation on a commercial scale. Aqua|still's technology consists of a modular building approach in designing and building plants which keeps costs low and ensures easy transport. At the same time this technology guarantees a high level of reliability, flexibility and efficiency in a number of different fields.

  • Hydrophobics

    Our technology uses hydrophobic membranes to separate pure distillate from warm water. Water vapor transport through the membrane takes place due to a pressure difference over the membrane caused by the temperature difference. Because the Aqua|still modules house a continuum of evaporation stages in an almost ideal countercurrent flow process, a very high recovery of evaporation heat is possible.

  • Vapor

    The temperature difference over the membrane causes water vapor to diffuse from the hot side of the membrane to the colder side of the membrane. This process of evaporation and condensation will cool down the hot side and heat up the colder side.

Aqua|still's technology is an unique concept which combines natural processes, advanced materials and state of the art production techniques to provide a low-cost solution for one of the world's greatest needs: purified water. Aqua|still's technology offers a sustainable solution for the provision of all kinds of water qualities. Economic growth is threatening the availability of fresh water in many regions in the world. Although seawater is abundant, conventional purification techniques consume considerable amounts of energy.
