Membrane Fine Bubble Disc Diffuser
As the most advanced aeration technology developed in the 1980s, membrane disc diffusers feature:
Ultra-fine bubble generation (1-2mm diameter)
Maximized gas-liquid contact area
Uniform bubble distribution
Clog-resistant design
Superior corrosion resistance
However, long-term operational challenges emerged:
× Membrane detachment
× Tearing failures
× Membrane inflexibility
× Sludge infiltration into air ducts
Through collaborative R&D with leading global institutions, our
company has:
✓ Incorporated international best practices
✓ Overcome critical technical barriers
✓ Revolutionized membrane diffuser design
✓ Developed next-generation disc diffusers meeting 21st century
international standards

"Precision-engineered for extreme durability:
• Reinforced piping system with 38% increased wall thickness + dual
support stands resists hydraulic/thermal fatigue
• Proprietary PTFE membranes maintain stable DWP (+/- 5%) while
reducing energy consumption by up to 15% vs standard membranes"
