Membrane Type Micro-Pore aerator:

1. The gas diffusion rubber plates of the aerator are made of the high quality synthetic rubber; the diameters of the diffused gas bubbles by the rubbermembrane are small, the area of the gas-liquid interface is big; so the aerator has the higher masstransfer speed and oxygen-charging efficiency. Comparing with other existing aerators, it can greatly reduce the power-consuming and the waste-water treatment cost.
2. There are a lot of the self –closing pores in the rubber membrance; the pores can automatically open and close along with the oxygen-charging and operation –stop; so there is no pore –blockage or contamination. And, the air which enters into the aerator do not need the dust removal puritication; when the aeration tank stops the operation, the sewagemixture will not flush back; these will reduce a lot of the operation cost and the maintenance workload.
3. As the membrane type micro-pore aerator can be successively arranged on the bottom of the aeration tank, the oxygen can be dissolved uniformly in the tank; the aerator can be used in all tank sand heights; and the aerator can also be used to renovate the existing aeration tanks, the efficiency of there novated aeration tanks can be improved.
4. As the gas diffusion plates of the membrane type micro-pore aerator are made of the high quality rubber, it has great physical and mechanical performances; the pallets, fittings and te air pipes adopts the engineering plastics; so there is no rust problem ,it greatly reduces the operation and maintenance workloads.
