SSI ECD215 Disc Diffuser System – Advanced Aeration for Biological Wastewater Treatment

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
