In practical projects, when fine bubble diffuser working, we find that the region of the highest stress is mainly in the outer edges and central membrane. As a result, the stretching of membrane with traditional design is limited, the membrane is in a high stress state for some time, it is very fragile and easy tear, furthermore faces high aeration resistance.Under such condition, the oxygenation capacity decreases, the power consumption and maintenance cost increase.
