método para controlar a concentração de íons em um líquido e dispositivo de purificação de líquido para controlar a concentração de íons em um líquido

摘要

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.
