UF8040-PVDF Enhanced Hollow Fiber Membrane

I.Enhance the characteristics of composite PVDF hollow fiber membrane:

• High strength: The reinforced composite PVDF hollow fiber membrane adopts a unique support layer film-making technology, so that its tensile strength and compressive strength are much higher than that of ordinary hollow fiber membrane. The tensile strength of a single fiber is greater than 50KG, and it is vividly called “the membrane that can not be pulled”.
• Good anti-pollution performance: The enhanced composite PVDF hollow fiber membrane has excellent anti-pollution performance due to its ultra-smooth membrane surface characteristics and unique charge performance, which are achieved by using PVDF alloy formulation as its filter layer.
• Ultra-high flux: The enhanced composite PVDF hollow fiber membrane adopts relatively independent special support layer technology and PVDF alloy membrane filtration layer technology, resulting in high porosity of the filtration layer. The produced membrane is not only strong but also has good flux.
• Good retention performance: The enhanced composite PVDF hollow fiber membrane uses PVDF alloy membrane as the filter layer, and its special internal and external dense double-layer structure makes it have superior retention performance.
• Good cleaning flux recovery: The enhanced composite PVDF hollow fiber membrane uses PVDF alloy membrane as the filter layer. Its special inner and outer dense double-layer structure makes the pollutants only stay on the outer surface of the membrane and will not enter the mesh pores of the membrane, so it is very easy to clean and the cleaning flux recovery is good.
• The composite PVDF membrane has good chemical stability, acid and alkali resistance, bacterial corrosion resistance and good oxidation resistance.

1. Product application fields:
2. Pre-treatment of purified water and pure water: sterilization and turbidity purification of tap water, groundwater and surface water (mountain spring water, reservoir water); pre-treatment of pure water equipment such as reverse osmosis and nanofiltration.
3. Separation and concentration of biopharmaceuticals and food and beverage: separation and concentration of plant extracts, antibiotics, proteins, amino acids, enzyme preparations, milk, soy milk, yellow wine, soy sauce, vinegar, etc.
4. Recovery and concentration of special liquids: recovery and concentration of electrophoretic paint, electroplating wastewater, waste alkali liquid, waste acid liquid, waste solvent, etc.
5. The performance of polyvinylidene fluoride (PVDF) alloy hollow fiber membrane is superior.

The membrane module adopts polyvinylidene fluoride (PVDF) alloy hollow fiber membrane, which has high strength, good anti-pollution, good oxidation resistance, good retention performance, large water production flux, good hydrophilicity and good cleaning flux recovery.

5. The external pressure structure makes the cleaning more convenient and thorough. The membrane module adopts the external pressure structure which is not easy to block, has better water flow distribution, larger filtration area and higher sewage interception capacity, so that the cleaning of the module is more convenient and thorough.
6. Full Flow Filtration, low energy consumption, and low operating costs. The membrane modules primarily operate in full flow filtration mode, which has lower operating pressure and energy consumption compared to cross-flow filtration, thus resulting in lower operating costs. However, the modules can also be easily converted to cross-flow filtration mode, allowing for the processing of water with poorer quality. Therefore, the specific operating mode should be determined based on the quality of the raw water.
7. Constant Flow Method, Simple Operation. Membrane modules often operate in a constant flow mode, with the transmembrane pressure difference gradually increasing over time. At this point, flux recovery is achieved through regular backwashing, air washing, and chemical cleaning. Adding biocides to the backwash water can effectively control microbial proliferation within the membrane module, thoroughly removing contaminants from the membrane surface.
8. High degree of automation and convenient management The membrane components are generally controlled by PLC throughout the process, which is convenient to manage.
