Abstract
A diffuser apparatus which has fine pores is capable of achieving a high oxygen transfer efficiency and rarely becoming clogged so that the apparatus can be operated stably over a prolonged period. The diffuser apparatus includes: an aeration plate that is disposed in an aeration tank in order to release pressurized air, fed from a diffusing air feed pipe, as air bubbles from fine pores formed in an aeration plate surface; blow water feeder for feeding blow water into the diffusing air feed pipe; and an inserted pipe for discharging the blow water, fed into the diffusing air feed pipe, from the aeration plate.
