1.     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, meanwhile the membrane is easy to tear and faces high aeration resistance.Under such condition, the oxygenation capacity decreases, the power consumption and maintenance cost increase.

       In order to avoid the abovementioned defects, we thicken the outer edges and central membrane. Such designs greatly improve the service life of YULONG® fine bubble diffuser.
