What is Pvdf Ultrafiltration Membrane and How Does It Work?
Pvdf Ultrafiltration Membrane and How Does It Work? PVDF ultrafiltration membranes, made of polyvinylidene fluoride, are widely used in various fields such as water treatment, food processing, and pharmaceutical manufacturing. These membranes are known for their chemical resistance, ability to withstand high temperatures, and mechanical strength. PVDF ultrafiltration membranes selectively retain particles more significant than a specific size while allowing smaller particles to pass through. Typically, the pore size of these membranes ranges from 0.001 to 0.01 microns, enabling them to effectively remove contaminants like bacteria, viruses, proteins, and other macromolecules from water. Compared to flat sheet membranes, PVDF ultrafiltration membranes are commonly produced as hollow fibres, which offer several advantages. Hollow fibres have a higher surface area-to-volume ratio, increasing efficiency. They are also easier to clean and maintain and can be conveniently assembled
