Abstract:
An ultrafine bubble cleaning apparatus uses a liquid containing ultrafine bubbles having a size of less than 30 nm to rinse fine particles adhered to soil, sand, etc. to separate and collect the fine particles. The ultrafine bubble cleaning apparatus includes a water tank-shaped reservoir, a stirring device, a supernatant discharge device including a pump for discharging a supernatant of the liquid in the reservoir, and a sedimentation extraction device. Substances are loaded into the ultrafine bubble-containing liquid stored in the reservoir, and the ultrafine bubble-containing liquid is repeatedly brought into contact with the surface of the substance using the stirring device. When ultrafine bubbles get into a space between fine metal particles adhered to the surfaces, cracks, and pits of the substances to be cleaned (including metal ions) and fine particles of organic substances including a solvent, a chemical, and oil, the fine particles are separated and floated.

Claim (Index 3):
An ultrafine bubble cleaning method comprising: swirling water in a storage type pressurized liquid tank in a full state all the time, the water is containing ultrafine bubbles having a size of 3 \u212b or more and less than 10 \u212b and bubbles larger than the ultrafine bubbles to concentrate a part thereof that contains the ultrafine bubbles and has a relatively large specific gravity outside a swirling flow, and concentrate a part thereof that contains bubbles larger than the ultrafine bubbles and has a relatively small specific gravity to a central part of the swirling flow followed by discharge from the storage type pressurized liquid tank; and mixing and stirring the ultrafine bubble-containing water containing the ultrafine bubbles that is concentrated outside in raw water in which fine droplets of an organic substance, are dispersed to attach the ultrafine bubbles to the fine droplets and cause the fine droplets to be floated and separated due to buoyancy of the ultrafine bubbles.
