Fine Bubble Membrane Diffuser Tube or Disc Type High Oxygen Transfer Efficiency
Aeration equipment is a core device in sewage treatment. By infusing air into water, it increases the dissolved oxygen content in water, provides sufficient oxygen for microorganisms, helps them decompose organic pollutants in sewage, and improves the efficiency of sewage purification.
Product Parameters
The flat-plate diaphragm aerator, developed in the 1980s, features small aeration bubble diameters, a small gas-liquid interface diameter, a large gas-liquid interface area, uniform bubble diffusion, no clogging, and strong corrosion resistance.
- Aerator Dimensions: φ215mm, φ260mm, φ300mm
- Service Area: 0.25-0.55㎡/unit, 0.35-0.75㎡/unit
- Average Pore Size of Aeration Membrane: 80-100µm
- Air Flow Rate: 1.5-3m³/h
- Total Oxygen Transfer Coefficient: kla (20°C) 0.204-0.337min-1
- Oxygen Utilization Rate: (Water Depth 3.2m) 18.4-27.7%
- Oxygenation Capacity: 0.112-0.185kgO²/m³/h
- Oxygenation Power Efficiency: 4.46-5.19kgO²/kWh
- Aeration Resistance: 180-280mmH₂O
Air pipe design should consider pressure balance and form a ring network. Each inlet pipe group should be equipped with a valve to facilitate air volume adjustment. Designed flow rate for air pipes: 10-15 m/s for main pipes and 5 m/s for branch pipes. Installation height of aerator surface from pool bottom: 270mm, 250mm, 200mm for push-plate type.
Advantages
Flat-plate diaphragm aerators feature small bubble diameters, a small gas-liquid interface diameter, and a large gas-liquid interface area, ensuring uniform bubble diffusion without clogging. They also offer strong corrosion resistance.
Testing has shown that these devices reduce energy consumption by 40% and increase wastewater treatment capacity by 40% compared to conventional fixed spiral aerators, diffused flow aerators, and perforated tube aerators.
They are particularly suitable for urban sewage treatment, the construction and expansion of large industrial plants, and the renovation of existing aeration tanks. Furthermore, these aeration tanks can operate intermittently.
