PURPOSE:To dissolve the choking of devices by slimes and to contrive the reduction of the maintenance cost and stabilization of the operation of the water circulating system, by a method wherein ozone is injected in the water at the entrance side of the devices such as a heat exchanger and strainers of the water supplying system, and slimes are sterilized and stripped off. CONSTITUTION:A heat-up brine pump 32 is operated after the ozone adsorption operation is repeated and necessary ozone is adsorbed, and heat-up medium in a brine tank 31 is sent in a heat-up fin 30 in an adsorption tower 26, and when the temperature in the tower becomes about 0 deg.C, the injection of ozone is begun. Next, an ejector pump 22 is started and after an ejector 21 has begun normal operation, a control valve 35 of an ozon supplying pipe from the ozone adsorption tower 26 to the ejector 21 is opened and the ejector 21 performs reaction and mixing of ozone containing gas and treating water. By repeating above-mentioned operation, ozone can be intermittently injected in the treating water at the necessary ozone density. Thus, slimes are sterized and stripped off, and the choking of the devices is dissolved and the operation can be stabilized. |
