ABSTRACT:
Water (23) that contains micro-nano bubbles generated in a micro-nano bubble generation tank (6) is introduced and treated in a charcoal water tank (ii) which is filled with a charcoal (15) and in which an air diffusing pipe (12) is placed and thereafter introduced and treated in a membrane device (21). Thus, activities of microorganisms propagating in the charcoal (15) 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 (21). 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 (6), 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 (21).
