<p>Provided is an air microbubble diffuser which generates air microbubbles ensuring high oxygen transfer efficiency. Further, the air-diffusing unit in the air microbubble diffuser need not be replaced even when clogging occurs in the unit. The air-diffusing unit is produced by superimposing multiple ring-shaped discs which each have one uneven surface formed by embossing, blasting, etching, laser or paper treatment, or the like, thus bearing fine pores. The air-diffusing unit, which generates air microbubbles, is disassemblable and therefore can be repeatedly used through reassembly after the removal of causal substance of clogging by washing.</p> |
