PURPOSE:To certainly perform the regeneration of an ion exchange resin, by confirming the concn. and use of brine at the time of the regeneration of the ion exchange resin. CONSTITUTION:Brine 3 for regenerating an ion exchange resin 1 is stored in a brine tank 4 and a control valve 5 used in alternately performing the softening of hard water and the regeneration of the resin 1 is clamped to a resin cylinder 2. In this apparatus, a sensor 9 is provided in the brine region (between the level A7 and the level B8) in the tank 4 corresponding to the amount of brine used when the resin 1 is regenerated while a control apparatus 10 receives the electric signal from the sensor 9 when the resin 1 is regenerated and, when the electric signal amount is equal to or less than a set value (the amount of a brine concn. confirming signal), a brine concn. deficient alarm is issued and, when equal to or more than the set value, a brine supply signal is outputted and, thereafter, when the supply signal amount reaches the set value, the brine supply signal is stopped. By this method, the regeneration of the ion exchange resin can be surely performed. |
