Abstract
The present invention provides an ozonization apparatus which is not only capable of dissolving ozone in material water with high efficiency and speedily but also enables the easy and proper control of the dissolved ozone concentration of ozone water. The present invention relates to an ozonization apparatus comprising an ozone gas-permeable membrane disposed to isolate material water and ozone gas from each other and allow said ozone gas to be dissolved in said material water by permeation, said ozone gas-permeable membrane being a nonporous hollow tube which is selectively gas-permeable and liquid-impermeable.
Claims17
An ozonization apparatus comprising
- an ozone gas-permeable membrane disposed to isolate material water and ozone gas from each other and allow said ozone gas to be dissolved in said material water by permeation, said ozone gas-permeable membrane being a nonporous hollow tube which is selectively gas-permeable and liquid-impermeable,
- wherein the ozone gas-permeable membrane is a membrane consisting of a tetrafluoroethylene resin polymer or a fluorine-containing rubber, and has a tube wall thickness of not more than 0.2 mm.
An ozonization apparatus comprising
- an ozone gas-permeable membrane disposed to isolate material water and ozone gas from each other and allow said ozone gas to be dissolved in said material water by permeation, said ozone gas-permeable membrane being a nonporous hollow tube which is selectively gas-permeable and liquid-impermeable,
- wherein the ozone gas-permeable membrane is a membrane consisting of a silicone resin and has a tube wall thickness of less than 1 mm.
An ozonization apparatus comprising
- a degassing module for removing dissolved gases from the material water,
- an ozone dissolution module for dissolving ozone gas in the degassed material water to prepare a primary ozone water, and
- an ozone concentration adjusting module for removing a necessary amount of dissolved ozone gas from said primary ozone water to control the dissolved ozone gas concentration and thereby provide a secondary ozone water.
