Product Introduction


 


Since 1995, YULONG®-AERATION has sold more than 2.5 million fine bubble wastewater diffusers worldwide. Our core competence and sole focus is engineering, designing, and client support for bubble diffuser assemblies and membranes.

Features


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.

2. Double check valve, periphery fold sealing                   3. Imported EPDM material from France


structure can prevent diaphram dropping off from 


the PP plate.

4. Unique porous technology makes the disc air diffuser bubble release evenly, with High Oxygen Transmission efficiency (OTE)


5. Good effect on saving in power, and low operating cost


6. The membrane has good self-cleaning and anti-clogging property


7. Easy to exclude failure, easy maintance and management


8. Simple structure for easy installation


9. Project cost is lower.
