Membrane filtration pursues tiny opportunities.

Prepared Foods | June 1, 1990| | Copyright

Concentration without evaporation, pasteurization without heating, demineralization without distillation, fractionation without chemistry-the food applications for membrane separation technology continue to grow since reverse osmosis membranes were first developed 25 years ago.

Like filtration . . .

Membrane separation is analogous to filtration, but using an exceedingly fine filter. Membranes filter molecules rather than particles and the permeability of membranes to molecules is as much a function of the membrane's physical and chemical properties as the ...
