Title:
ULTRAFINE BUBBLE GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/183891
Kind Code:
A1
Abstract:
The present invention relates to an ultrafine bubble generating device for biological treatment of contaminated water, which uses the air lift effect to diffuse contaminated water mixed with micro bubbles throughout a reaction tank so as to supply dissolved oxygen to bacteria which break down organic matter and prevent sludge from accumulating on the floor of the reaction tank. Also, a method is used in which cavitation is accelerated in order to generate more micro bubbles using a small amount of energy, and the portion generating friction with the contaminated water is made of durable materials, and the surface is made smooth, so as to be advantageous in terms of maintenance control.
