理能力を推定する公知例は、見あたらない。Conventionally, as a method to measure the processing capacity of water treatment equipment using ion exchange resin, which is commonly used as an ion exchange medium, ions at an appropriate concentration are continuously loaded into a column with a resin packing height that simulates the actual equipment. A method has been adopted in which the outlet water quality is monitored by electrical conductivity, and the treatment capacity is determined from the time until the treated water quality deteriorates and the cumulative ion load up to that point. However, there is no known example of estimating the overall processing capacity from the performance per unit amount.

っていた。The above-mentioned conventional technology does not give consideration to performance evaluation such as being able to respond to transient concentration changes, and therefore has the problem that it is impossible to predict the properties of the outlet water when the processing capacity is used up. In the conventional technology, the measure was taken to perform regeneration processing with sufficient margin for the design load amount, so there was no need in actual operation to understand the transient performance in particular. Because regeneration is repeated over and over again, there is a heavy economic burden, including waste treatment costs, regeneration chemical purchase costs, and labor costs for regeneration operations.
