WATER TANK EQUIPPED WITH FINE BUBBLE GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a water tank equipped with a fine bubble generator which can control escape of fine bubbles out of the tank due to buoyancy so as to make the bubbles reside everywhere within the tank for a long time.

SOLUTION: The tank is so constructed as to discharge, into the tank, a water flow containing fine bubbles 3 generated by dissolving a gas in water and then causing the gas to precipitate. An electrode 5 for attracting fine bubbles 3 in a charged state is arranged on the bottom surface 4 of the tank 2. The electrode 5 attracts charged fine bubbles 3 toward the bottom surface of the tank 2 against buoyancy.
