Transmembrane Pressure (TMP)
The average differential pressure from the upstream side of the membrane (applied pressure) and
downstream side (permeate).
Ultrafiltration (UF)
A filtration technique that uses controlled pore, semi permeable membranes to concentrate or
fractionate dissolved molecules. Molecules much larger than the pores are retained in the feed solution
and are concentrated in direct proportion to the volume of liquid that passes through the membrane.
Molecules whose size are close to that of the pores, concentrate to a lesser extent with some of the
molecules passing through the membrane in the permeate. The concentration of freely permeable
molecules (salts) in the sample remains essentially unchanged.
