Method for treating untreated brine to produce process water, process water produced thereby, and apparatus for performing said method

摘要

The present invention relates to a method of treating an untreated saline water (RW), a process water (PW) thereby produced, and a device for carrying out said method. The method includes the steps of: a) furnishing the untreated water (RW); b) producing a mixture (M) by mixing the untreated saline water (RW) with an aqueous solution (HL) containing hydroxide ions; c) sedimenting the solid (FS) forming from the mixture (M) with concurrent formation of an essentially clear supernatant (U); and d) withdrawing process water (PW) from the essentially clear supernatant (U).
