Abstract
Water () that contains micro-nano bubbles generated in a micro-nano bubble generation tank () is introduced and treated in a charcoal water tank (ii) which is filled with a charcoal () and in which an air diffusing pipe () is placed and thereafter introduced and treated in a membrane device (). Thus, activities of microorganisms propagating in the charcoal () are increased by the micro-nano bubbles, markedly increasing ability of decomposing organic matters in the water. Therefore, a clogging phenomenon due to the organic matters can be prevented by reducing organic loads on the membrane device (). Moreover, a very small amount of alcohols or salts are added as a micro-nano bubble generation aid to the micro-nano bubble generation tank (), improving an incidence rate of the micro-nano bubbles. The alcohols and salts are easily decomposed by the charcoal water tank (ii) and easily removed by the membrane device ().
