  • FUNCTIONAL WATER PRODUCING APPARATUS AND FUNCTIONAL WATER PRODUCING METHOD
    Publication number: 20200353431
    Abstract: A functional water producing apparatus in an embodiment includes: a water pressure regulator configured to regulate the water pressure of the ultrapure water, the water pressure regulator having a pressure regulating valve configured to regulate a water pressure of the ultrapure water to an almost constant pressure and a feed water pump configured to pressurize the ultrapure water; a dissolving device configured to dissolve functional gas imparting a specific function in the ultrapure water regulated the water pressure by the water pressure regulator; and a control device configured to control the feed water pump to regulate the water pressure of the functional water to a predetermined constant pressure based on a water pressure or a flow rate of the functional water flowing out of the dissolving device.
    Type: Application
    Filed: April 7, 2020
    Publication date: November 12, 2020
    Applicants: NOMURA MICRO SCIENCE CO., LTD., ACM RESEARCH (SHANGHAI), INC.
