PROBLEM TO BE SOLVED: To provide a monochloramine preparation apparatus capable of safely and suitably preparing monochloramine for use in the sterilization of a system for water to be treated such as hot spring water, bathtub water, or pool water, while avoiding the mixture of a chlorine agent with an ammonia agent under high concentration.SOLUTION: A monochloramine preparation apparatus 1 comprises: a water supply part 10 for supplying water; a chlorine agent supply part 30 for supplying a constant flow rate of a chlorine agent to the water supplied from the water supply part 10, according to the flow rate of the water; an ammonia agent supply part 40 for supplying a constant flow rate of an ammonia agent to the water supplied from the water supply part 10, according to the flow rate of the water; and a flow rate sensor 21 as a flowmeter for measuring the water flow rate of the water supply part 10. A normal flow rate range of the water of the water supply part 10 is set in the flow rate sensor 21. When a measured water flow rate is within the normal flow rate range, the flow rate sensor sends a drive signal S3 to the chlorine agent supply part 30 and to the ammonia agent supply part 40. The chlorine agent supply part 30 and the ammonia agent supply part 40 supply the chlorine agent and the ammonia agent respectively during the reception of the drive signal S3.SELECTED DRAWING: Figure 1 |
