Hollow Fiber Membrane Filtration is a sophisticated separation technology, The membranes consist of long, hair-like hollow fibers grouped tightly in a cylindrical shell. Each fiber functions as a semi-permeable barrier, guiding fluid flow either inside or outside the fibers.
As fluid passes through the fibers, particles larger than the membrane's pore size (which can vary from microns down to nanometers) are retained, while smaller components pass through, resulting in purified fluid. The TFF filter membrane size of the pores in the membrane dictates what can pass through.
