♦Main functions & structure：

This equipment utilizes a hydrophobic high-polymer long-fiber membrane as the diffuser surface, which has been specially treated for a smooth finish. The membrane features ultra-fine pores (approximately 0.05 μm, invisible to the naked eye), with over 6,000 pores per cm², enabling the uniform generation of radially dispersed ultra-fine bubbles that effectively enhance oxygen transfer efficiency. The system is designed for low pressure loss, operating at less than 200 mmAq (water column).

Thanks to the unique membrane structure, no additional check valve is required, and the risk of water backflow is extremely low, simplifying installation and subsequent maintenance.

The product also demonstrates excellent mechanical strength, with the membrane tested to exceed 10 kg/25 mm tensile strength and maintain a low elongation rate below 20%. This makes it particularly suitable for aeration in deep tanks, providing outstanding durability and performance.

⚠️ Note: Due to the ultra-fine pore size of the membrane, ensure the internal piping is clean and free of debris during installation to prevent clogging and maintain optimal performance.

♦Features：

The diffuser membrane is fabricated from a high-performance polymer material, characterized by:

• Thermal stability, enabling continuous operation at temperatures up to 90°C

• Excellent resistance to aging and ultraviolet (UV) degradation, ensuring prolonged service life

• Structural stability and lightweight construction for ease of installation and reliable performance

• Superior gas permeability facilitating efficient oxygen transfer

• High chemical resistance, with strong tolerance to acidic and alkaline wastewater conditions

• Low aerodynamic pressure loss, optimizing energy consumption in aeration processes

♦High oxygen transfer efficiency：

When air passes through the diffuser, over 6,000 fine pores evenly distributed across the membrane continuously generate ultra-fine bubbles with a diameter of approximately 0.05 μm, significantly increasing the air–water contact area. According to testing conducted by the Industrial Technology Research Institute's Environmental Research Division, this design effectively enhances oxygen transfer efficiency in water by more than 26%.
