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.
Claims10
A diffuser apparatus, comprising:
- 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 feeding means for feeding blow water into said diffusing air feed pipe against an air pressure of said diffusing air feed pipe;
- and
- discharging means for discharging said blow water, fed into said diffusing air feed pipe, from said aeration plate
- wherein said discharging means is constituted by an inserted pipe, an upper end of which communicates with said aeration plate and a lower end of which is inserted into said diffusing air feed pipe, and
- wherein said diffusing air and said blow water are fed to said aeration plate through said inserted pipe by feeding said blow water to said diffusing air feed pipe by said blow water feeding means.
