SSI ECD215 Disc Diffuser System – Advanced Aeration for Biological
Wastewater Treatment
Reinforced Membrane Locking System
The diffuser cover features a downward-protruding rim with multiple
locking bars positioned beneath the extension and within the
support coil groove. Utilizing a thickened 10mm diameter membrane
cord, the assembly process involves lifting the cover to securely
fasten the membrane into the support disc's groove. The integrated
ribs interlock with the internal rubber membrane, creating a dual
sealing mechanism that completely prevents membrane detachment.
Enhanced Structural Design
Thread root reinforcement prevents fracturing under cyclic loading
Optimized airflow channel geometry increases gas passage area by
30%
Precision chamfering at all critical angles reduces operational
pressure loss by 15-20%
Anti-Creep Retention Mechanism
Six L-shaped clamping bars arranged radially around the diffuser
cover:
• Counteract long-term plastic deformation from membrane expansion
pressure
• Maintain constant sealing force throughout operational cycles
• Eliminate membrane slippage even under continuous dynamic loading
Key Features & Benefits
"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"
