3. Crossflow Microfiltration of particle Suspensions - The influence of hydrodynamics and physico-chemical interactions
Abstract : Crossflow microfiltration is a technique to separate suspended particles (or cells or droplets) from liquids by use of a membrane that is permeable for the liquid but impermeable for the particles. The permeate flow drives particles to the membrane surface, where they may be deposited and form a fouling layer. READ MORE
