Production of soft water comprises regeneration of an ion exchanger during a regeneration phase by a regenerator solution in a reservoir, and addition of a sodium chloride and sodium sulfite to the solution

摘要

The reservoir (12) is connected with the ion exchanger (10), which is transferred in regular time intervals with the sodium chloride (1-5 g/l) (18), and introduced a T-piece of a regenerator line (22) in the regenerator solution (14). The chloride containing regenerator solution is electrolyzed in a flow cell (20) between two electrodes (50) under polarity reversed DC voltage. An independent claim is also included for an ion exchanger plant with the ion exchanger.
