Pioneering Water Treatment with PVDF Ultrafiltration Membranes

For creatures to thrive, they require water, yet freshwater is only found in a small portion of the water that is readily available1, 2. Dyes are one of the main contaminants found in wastewater discharged from a variety of sectors, mostly textiles, and paper, and they pose a danger to human health as well as negatively impact the environment.3. Textile industrial dyes are characterized by their complicated structures, large molecular weight, non-biodegradability, and hazardous reactants.

Additionally, the development of aquatic plants is hampered by dyes that act as a barrier to light emission, hence cleaning such effluents is essential4,5. Adsorption, membrane separation, coagulation, and chemical/photocatalytic oxidation are frequently used techniques for handling wastewater containing dyes6.

Membrane separation methods with high efficiency, low energy consumption, and simplicity of operation have drawn increased attention because of the high energy requirements and restricted reusability of conventional treatment technologies7,8. Pressure force membrane procedures include reverse osmosis (RO)13, ultrafiltration (UF)11, nanofiltration (NF)12, and microfiltration (MF)9, 10. The UF method is frequently used to clean water that has been contaminated by various dyes14.

We at Hinada are a proficient manufacturer of ultrafiltration membranes and membrane bioreactors! Our MBR modular system, which uses cutting-edge MBR technology, offers several benefits, including easy maintenance and cleaning, a prefabricated MBR system, PVDF MBR membrane, reduced energy costs, high-quality effluent, a smaller footprint, high flow rate, and more. Moreover, it is a convenient biological solution that is both easy to carry and install. For your wastewater treatment plant projects, we provide tailored service and PVDF membranes in any size.

Because of its exceptional mechanical strength and low protein adsorption characteristics, PVDF Hydrophilic Membrane Filters are widely employed in the preparation and sterilization of biological samples, including the filtering of protein solutions and the purification of cell culture medium. High throughput and low loss filtration performance are offered by polyvinylidene fluoride hydrophilic membrane filters, which are especially well-suited for applications requiring a high degree of purity and sample recovery. The reputation of PVDF Polyvinylidene Fluoride Hydrophilic Membrane Filters stems from their exceptional strength and resilience to chemicals.

Features:

1. It is a hydrophilic membrane that exhibits good resistance to solvents.
2. It works exceptionally well to stop sample solvent leaks and can guarantee membrane area usage in a wide filtration area.
3. PVDF ultrafiltration membranes are hydrophilic indefinitely.
4. PVDF UF membrane module offers longer service life and a bigger filtering area.
5. PVDF hollow fiber ultrafiltration membrane has robust resistance to oxidation, as well as acid and alkali.
6. PVDF hollow fiber UF membranes are uniformly micropore distributed and have high mechanical strength.
7. PVDF membrane modules employ clamps with worldwide standard sizes for effortless replacement and fast installation.

PVDF Hydrophilic Membranes are often utilized in biomedical processes, including the processing of clinical samples, the sterilization of cell culture medium, and the filtration of proteins and enzymes. Polyvinylidene Fluoride Hydrophilic Membranes are ideal for delicate and exact experimental settings, and they provide a high level of biocompatibility.

PVDF ultrafiltration membrane is used in verities of solutions like:

1. Desalination of seawater
2. Reusing recovered water
3. Prefiltration using reverse osmosis
4. Wastewater treatment in power plants
5. Treatment of wastewater by electroplating
6. Reusing deep treatment for industrial wastewater

High-grade anti-pollution PVDF (Polyvinylidene Fluoride) membrane material with strong oxidation resistance, acid and alkali resistance, and chemical stability makes up Hinada’s PVDF Ultrafiltration Membrane Module. For high throughput, the PVDF ultrafiltration membrane is hydrophilic indefinitely. The homogeneous distribution of pore sizes in the PVDF hollow fiber UF membrane fiber ensures consistent high-quality water. PVDF hollow fiber ultrafiltration membranes have a long service life because they are easy to backwash, have a greater surface filtration area, and have superior mechanical strength.

PVDF, or polyvinylidene fluoride, is an excellent material for UF polymeric membrane production because of its strong mechanical properties, excellent chemical resistance, and thermal stability15. Because PVDF membranes are less hydrophilic or more hydrophobic than other membrane types, proteins and organic materials can foul the membrane during the wastewater treatment process. Membrane fouling raises energy expenditures while lowering lifetime and water flux16. As a result, membrane hydrophilicity is considerably reduced9.

Such membranes may be made more hydrophilic and anti-fouling by employing a variety of ways. One such technique is the incorporation of inorganic nanoparticles into the membrane matrix, which increases the membranes’ hydrophilicity and anti-fouling properties. By using the phase inversion (PI) method to construct the PVDF-SiO2 composite membrane, Wu et al. demonstrated that the addition of SiO2 enhanced the membrane’s fouling resistance17.

Yan et al. used the PI approach to create modified PVDF/Al2O3 membranes. Al2O3 nanoparticles improved the membrane’s anti-fouling efficacy and permeation flow in comparison to the unmodified membrane, according to AFM and SEM analyses18. Other nanoparticles that have been effectively used in membrane manufacturing to remove dyes are graphene oxide (GO)22, carbon nanotubes (CNTs)21, ferroferric oxide (Fe3O4)20, titanium dioxide (TiO2)19, and graphene oxide (GO).
