OZONATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an ozonation system which suppresses reduction of the concentration of ozone water in an ozonation device as a use point of the ozone water, prevents the scale of ozonation device from being increased and prevents the degree of cleanness of used raw water from being lowered. SOLUTION: An ozonizer 11 is installed on the site remote from the ozonation device 20 which performs ozonation such as cleaning treatment by using ozone water and an ozone dissolver 22 is disposed on the inside of the ozonation device 20. Ozone gas generated by the ozonizer 11 is supplied to the ozone dissolver 22 in the ozonation device 20 through a gas piping 40 as it is in gas state and the ozone water for ozonation is produced in the ozonation device 20.
