Conventionally driven high-pressure reverse osmosis plants for desalination are working on pressures of 80bar (1150psi) max. The company from succeeded in modifying their spiral wound elements in a way, that an operation pressure up to 120bar (1700psi) can be reached. By using the OSMO high- pressure reverse osmosis the obtainable concentration combined with a downstream evaporation is much more economical regarding investment and operation costs compared to a single evaporator.
The high-pressure reverse osmosis consumes about 10 times less energy than a comparable evaporation step. Additionally, the capacity of an existing evaporation plant can be increased enormously by a high-pressure reverse osmosis plant.
For testing this concept with liquids, where no experience exists, laboratory and pilot plants are available at OSMO.
