WATER PURIFICATION APPARATUS |
| 摘要 |
In a water purification apparatus, a light source irradiates the water, passing through the flow passage, with ultraviolet light. The light source has a light emitting diode that emits the ultraviolet light whose wavelength is contained in a bandwidth of 220 nm or above to less than 300 nm, and the optical output in this wavelength bandwidth is in a range of 1 W to 50 W. The flow passage passes the water at a flow rate of 5 mL/second to 250 mL/second. The flow passage is formed by a wall surface having a tubular shape. A window through which the ultraviolet light is passed is provided in at least part of the wall surface. |
