The evapeos® process harnesses the principle of osmosis. Water transfers across a membrane from the product to an extraction liquid, the osmotic agent. The transfer is due to an activity difference between the compartments on each side of the membrane. Moreover, only water can transfer across the membrane; the other compounds remain in the product.
This concentration is performed at ambient temperature and atmospheric pressure. Therefore, the product is concentrated under mild operating conditions and without direct contact with the osmotic agent.
After flowing to the membrane module the osmotic agent is regenerated continuously by thermal evaporation.
