Title:
FINE BUBBLE GENERATION DEVICE AND FINE BUBBLE GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/004653
Kind Code:
A1
Abstract:
A fine bubble generation device according to one aspect of this disclosure generates fine bubbles in a liquid by passing the liquid through a porous element having a plurality of pores. This fine bubble generation device generates fine bubbles by applying a pressure differential between one side and the other side of the element and, due to this applied pressure differential, causing the liquid disposed on the one side of the element to pass to the other side and be sprayed. The flow rate when the liquid passes through the element in the fine bubble generation device is no less than 0.009769 [m/s]. Thus, fine bubbles can be efficiently generated.
