SSI ECD215 Disc Diffuser System – Advanced Aeration for Biological
Wastewater Treatment
Self-Regulating Micro-Orifice Operation
The diffuser membrane's dynamic pores automatically expand during
aeration, enabling optimal airflow. When deactivated, the smart
pores contract to a fully sealed state, effectively preventing
clogging from suspended solids - a revolutionary solution to
chronic pore obstruction issues.
Integrated Anti-Backflow Protection
Our patented check valve system in the base plate:
• Instantly seals when air supply stops
• Blocks 100% of mixed liquor backflow
• Eliminates branch pipe clogging permanently
Breakthrough Maintenance-Free Design
Unlike conventional diffusers requiring 5μm pre-filtration, this
system:
✓ Operates flawlessly with unfiltered air supply
✓ Withstands intermittent aeration cycles
✓ Solves three industry-wide failures:
Membrane tearing from over-expansion
Membrane failure to open
Biofouling-induced clogging
Engineering Superiority
These technological breakthroughs deliver:
• 10+ years maintenance-free operation
• 60% reduction in lifecycle costs
• Unmatched reliability in SBR/CASS systems
*Certified performance: NSF/ANSI 61, ISO 9001:2015*
