| High Light | Wastewater Treatment Fine Bubble Disc Diffuser ，Aeration Performance Fine Bubble Disc Diffuser | ||
The fine bubble disc diffuser operates by forcing compressed air through a microporous diffusion disc, creating a dense cloud of fine bubbles. As these bubbles rise through the water, they facilitate gas-liquid contact, allowing oxygen to dissolve into the wastewater and increasing its DO concentration. Due to their small size (typically 1–3 mm in diameter), these bubbles provide a significantly larger surface area compared to coarse bubbles, maximizing oxygen transfer efficiency.
Key Advantages:
High Oxygen Transfer Efficiency (OTE): Microbubbles enhance mass transfer, reducing energy consumption.
Uniform Aeration Distribution: Ensures consistent DO levels throughout the tank.
Durable & Clog-Resistant: Advanced membrane materials minimize fouling and extend service life.
This technology is essential for energy-efficient and high-performance biological wastewater treatment.
"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"
