摘要

The desalination of seawater and other salt containing water e.g. brackish water by reverse osmosis, comprises mixing ozone to the solution to be desalinated before it is supplied to the reverse osmosis, leading the mixture over a ceramic ultrafiltration membrane in the dead-end-mode and subsequently over an adsorber, bringing the mixture from salt containing water and ozone directly below the ultrafiltration membrane, and cyclically backflushing the ultrafiltration membrane with permeate. An independent claim is included for a device for desalination of seawater and other salt containing water e.g. brackish water by reverse osmosis.
