UF Membrane Module Hollow Fiber PVDF For Wastewater treatment

1.High Filtration Precision, Delivering Reliable Purification Outcomes

The membrane boasts pore sizes typically ranging from 0.001 to 0.1 μm, enabling it to effectively intercept impurities including bacteria, viruses, colloids, large organic molecules, and suspended solids in water, while simultaneously retaining beneficial minerals (such as calcium and magnesium ions). The filtered water produced is crystal-clear, directly fulfilling fundamental purification requirements for drinking water, industrial process water, and various other applications.

2.High Flux and Enhanced Efficiency

4.The hollow fiber structure substantially amplifies the membrane's specific surface area (the effective filtration area per unit volume), leading to a higher filtration flux within the same volume. This facilitates the swift treatment of substantial water volumes, rendering it ideal for large-scale water treatment applications, including municipal and industrial wastewater treatment.

3.Low Operating Costs and Superior Energy Efficiency

The filtration process necessitates only a low operating pressure (typically between 0.1 and 0.3 MPa), resulting in significantly reduced energy consumption compared to advanced filtration technologies like reverse osmosis. Moreover, the membrane modules can be rejuvenated through backwashing and chemical cleaning, prolonging their service life (typically 3-5 years) and minimizing replacement expenses.

4.Robust Anti-Pollution Capability and Extensive Adaptability

Certain materials, such as PVDF membranes, exhibit resistance to acids, alkalis, and oxidation, enabling them to endure intricate water conditions, including highly contaminated industrial wastewater and high-salinity environments. Techniques like cross-flow filtration can mitigate pollutant deposition on the membrane surface, decelerating membrane fouling and ensuring stable operation.

5.Versatile Application Scenarios and High Compatibility

It can be employed independently as an advanced filtration unit or integrated with other processes (such as pretreatment, reverse osmosis, and nanofiltration). It exhibits high compatibility across diverse scenarios, encompassing drinking water purification, wastewater treatment and reuse, and industrial purification.

Polyvinylidene fluoride (PVDF) ultrafiltration membrane

This material is corrosion-resistant, antioxidant, acid- and alkali-resistant, and chemically stable. The membrane fibers utilize fiber composite manufacturing technology and undergo special processes, including permanent hydrophilic modification, to create a gradient mesh pore structure. Precise pore size control enables precise material separation, high recovery rates, and stable performance. Bacterial retention rates exceeding 4LOG are achieved, significantly improving water flux while maintaining stable performance.

- High Flux and Low-Temperature Resistance: The permanently hydrophilized PVDF material and gradient network pore structure provide exceptionally high permeability, increasing flux by 40% at the same low-temperature pressure differential.

- High Peel Strength: Utilizing a crocheted cord lining, securely bonded to the PVDF functional layer, the single-filament peel strength reaches ≥1.5 MPa, effectively eliminating membrane filament deformation, breakage, and the fragility of the functional layer, ensuring long-term stable water quality.

- Positioned Wire Arrangement Technology: Effectively prevents entanglement, tangling, and mud accumulation caused by cross-linking of membrane filaments. The soft rubber at the base of the membrane filaments provides a cushioning protection, effectively preventing breakage.

- Dry Storage: The PVDF membrane filaments produced through the composite modification process exhibit excellent chemical resistance and permanent hydrophilicity, making them easy to store, transport, and maintain.

Model Selection Recommendations:

- If the molecular weight of large organic molecules in the water being treated is between 10,000 and 30,000, the YX-UF-20K (MWCO 20,000) is preferred, as it accurately intercepts target substances.

- Membrane filaments with smaller inner/outer diameters (e.g., 0.4 / 0.6 mm) are suitable for compact equipment, provide faster water flow, and are ideal for low-contamination water. Membrane filaments with larger outer diameters (e.g., 3.5 / 5.0 mm) are more resistant to clogging and are suitable for high-turbidity water.
