What is Membrane Filtration Method? Definition, Summary

Membrane filtration method is an alternative to the MPN method for the microbiological analysis of water. Sometimes, it also refers as Millipore filter technique or MF technique. The Millipore filter technique was named by the two scientists Goetz and Tsuneishi in 1951.

Two basic models can be distinguished for mass transfer through the membrane
the solution diffusion model and
the hydrodynamic model.
In real membranes, these two transport mechanisms certainly occur side by side, especially during ultra filtration.

Membrane Filtration Technique. Membrane filtration technology provides an alternative to centrifugation. The patient's blood is pumped through a parallel plate or hollow fiber filter at a continuous flow rate, typically 50 to 200 mL/min (see Fig. 12 1 B). The membranes usually have pores of 0.2 to 0.6m diameter, sufficient to allow passage of plasma while retaining cells.
