Description

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
