Interception immiscible liquids

Membrane separators are us for immiscible liquid segregation. These devices are extensively covered elsewhere in this book. For actual segregation, ultrafiltration or microfiltntion membranes are another variation of an impaction or interception mechanism. Ultrafiltration membranes have discrete pores about 0.001-0.02 (im in diameter which allow the continuous phase to pass while trapping the much huger individual drops, which are usually greater than 0.1 pm. Row velocity across the membrane surface resuspends trapped dispersed-phase material to prevent blinding of the pores. Pressure drop requirements...
