Document Type and Number:
WIPO Patent Application WO/2019/138590
Kind Code:
A1
Abstract:
Provided is an effective method or system for shellfish purification. The shellfish purification method, which comprises preparing seawater in a pooling part, said seawater having been purified by ultraviolet light irradiation and containing oxygen gas bubbles, holding the seawater in the pooling tank while being in contact with shellfish, and then guiding out the seawater from the pooling part, is characterized in that the bubbles include ultra microbubbles having a diameter of less than 100 nm and these ultra microbubbles selectively adsorb/desorb viruses etc. accumulated in the shellfish. The shellfish purification system, which comprises purification parts purifying seawater by ultraviolet light, a ultra microbubble generation part generating oxygen gas bubbles having a diameter of less than 100 nm in the seawater and a pooling part connected to the purification parts purifying seawater by ultraviolet light and the ultra microbubble generation part and pooling the seawater, is characterized in that the pooling part holds shellfish therein.
