【Task】 The present invention provides a novel device for preparing a constant concentration biocide solution. More specifically, multiple solutions are prepared by dissolving the solid biocide in a controlled and monitored manner, which always have the same, constant biocide dose per unit volume. This new device overcomes a major drawback of existing solid biocide feeders, namely, a decrease in biocide concentration over time due to a gradual decrease in solid biocide in the supply vessel.
