Aquaculture Membrane Aeration Diffuser In Contact Aerator Pool
Product Description
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.
In order to avoid the abovementioned defects, we thicken the outer edges and central
membrane.Unique designs can greatly improve the service life of YULONG® fine bubble
diffuser.
Finds Application In :
1. Aeration for SBR reaction basin, contact oxidation pond, and activated sludge aeration
basin in sewage disposal plant;
2. Aeration for denitrification / dephosphorization aerobic processes;
  
3. Aeration for excreta and animal wastewater treatment plant;
  
4. Aeration of deep aeration basin;
  
5. Aeration for high concentration wastewater aeration basin, and aeration for regulating pond
of wastewater treatment plant;
  
6. Aeration of fishpond and other applications.
Features
1.Simple structure, ease of installation
  
2.Tight sealing without air leakage
  
3.Maintenance-free design, long service life
  
4.Corrosion resistance and anti-clogging
  
5.High oxygen transfer efficiency
