The AFS submerged ultrafiltration membrane relies on gravity or the negative pressure of a suction pump to drive the water to be treated through the micropores of the membrane filaments under a pressure difference. The water becomes produced water that enters the interior of the membrane filaments, that is collected and discharged through a water collecting pipe. Impurities such as suspended solids, colloids, bacteria, and macromolecular organic matter in the water are intercepted on the outer side of the membrane filaments, so as to achieve water purification and separation.
Compact footprint: As the membrane modules are directly submerged in the treatment tank, there is no need for additional pressure vessels or complex piping systems, thus saving significant space. This makes it particularly suitable for areas with tight land resources.Low energy consumption: Compared with pressure-type ultrafiltration membranes, submerged ultrafiltration membranes rely on gravity or low suction negative pressure for filtration, eliminating the need for high operating pressure and reducing energy consumption.Easy installation and maintenance: The installation and replacement of membrane modules are relatively simple, requiring no complex operations or equipment. Meanwhile, since the modules are submerged in water, routine inspection and maintenance are also convenient.Strong adaptability: It can be combined with other water treatment processes (such as biological treatment processes) to form an integrated treatment system, showing strong adaptability to different water qualities and quantities.
With a highly cross-linked, multi-channel, low-resistance membrane structure, the water production capacity per unit membrane area is increased by 10% compared to conventional designs.
With a homogeneous sponge-like membrane structure, the entire membrane filament serves as a filtration layer, achieving multi-layer screening for stable water quality.
With a completely open module structure, it leverages the advantages of submerged operation, features non-clogging performance, and offers broad tolerance.
With a cleaning pH range of 1 to 13.5 and tolerance to sodium hypochlorite cleaning at a concentration of 8,000 ppm, its through-structure allows pollutants to be more easily stripped and discharged.
With a dense membrane structure, the membrane filament strength is 2 to 3 times that of similar products. It is resistant to chemical cleaning and operates in a submerged open mode without filament breakage.
