Abstract (en)

[origin: WO2013020586A1] The invention relates to a method and a device for purifying liquids (3), in particular raw juice or vinasse, of unwanted accompanying substances (R), wherein a) first of all calcium hydroxide is added to a liquid (3) to be purified and b) then gaseous carbon dioxide (6) is introduced into the liquid (3) to be purified, in order to precipitate calcium carbonate which binds and/or entrains the unwanted accompanying substances (R). The method according to the invention is characterised in that in connection with step b) gas outlet openings (5b) for the carbon dioxide (6) are subjected to ultrasound (5f). Accordingly, in the device according to the invention the carbonation unit has ultrasound means designed to subject the gas outlet openings (5b) to ultrasound (5f). This counteracts calcination of the gas outlet openings and enables the introduction of small carbon dioxide bubbles, so that the process management is improved.
