A method for controlling the concentration of ions in a liquid comprises the steps of: generating a main stream (1) of liquid; applying a transverse electric field to the main stream by electrodes that are electrically in direct contact with the liquid; deriving a product stream (11) of liquid from the central region of the main stream, and waste streams (12, 13) of liquid from regions of the main stream closer to said electrodes.
