Filed: 1987-08-27
Abstract: PURPOSE:To accurately indicate resin capacity with time by detecting flow rate of raw water or brine at a time of water feeding and a time of regeneration, substracting and summing the resin capacity based on respective calculating elements. CONSTITUTION:At a time for water feeding, raw water is introduced from the upper part of a resin column 2 by the pressure of raw water and ion exchange with hardness components in raw water is performed by Na-type cation exchange resin 1. On the other hand, at a time of regeneration, brine is sucked through a brine line 6 by operation of a control valve 5 and resin is regenerated. Herein a calculating element at a time for water feeding is decided by substracting value which is calculated by both water feed amount measured with a flowmeter 10 and hardness of raw water from the residual capacity of resin as a negative component and therefore the calculating element at a time for regeneration is decided by adding value which is previously calculated from the passed amount of brine measured with the flowmeter 10 to the residual capacity of resin as a positive component. These output signals are successively sent to a controller.
