High oxygen transfer efficiency
There are 4400 holes which are almost on average on the surface of EPDM membrane, it can form 1-3mm bubbles (tiny, average, better flow rate, better flow status), it can also increase the contacting area with waste water. Even for less capacity disc diffuser, the OTE is the same.

Saving power
Because of high OTE, you can choose the economic blower to meet the DTR requirement of aeration process. OTE can be up to 25% (with condition: under 4M water depth and 2CMH wind capacity).

Excellent function for preventing backflow
The gas holes can be open and closed easily to prevent back flow phenomenon when the air conveying breaks off. It has good self-cleaning function; bubbles will ascend in a screw status.
