WATER QUALITY MANAGEMENT METHOD AND WATER QUALITY MANAGEMENT CHART FOR CIRCULATING WATER COURSE SYSTEM

Japanese Patent JP3119318

B2

PURPOSE: To quantitatively recognize the ease (generation intensity) of rust and scale so that the operation of a water treating device can efficiently be made by managing water quality with the concns. of various kinds of ions in a circulating water course system and the fluctuation coefft. of the concentration multiple of a solute concn. as the index.
CONSTITUTION: The measured values (a) of the concns. of various kinds of the ions and the solute in the circulating water course system entailing condensation of water and the measured values (b) of the various kinds of the ions and the solute in feed water to the circulating water course system are contrasted by each of the same kinds. The water quality is managed by defining the ratio of a standard deviation S at the concentration multiple X1 to the average concentration multiplex X which is the mean value of the concentration multiplex X1, i.e., fluctuation coefft. CV as an index if the ratio a/b of the measured values (a) to the measured values (b) is defined as the concentration multiplex X1 as the index. A vibrating magnetic field and electric field generator is used in such a manner that the fluctuation coefft. does not exceed 20%. This device is constituted by housing a 1/2 wavelength wire antenna 1 within a steel pipe 2, both ends 4, 4' of which are formed as an inlet and outlet for the water and connecting a high-frequency power source 3 to this antenna 1.
