Abstract

The application of corrugations as turbulence promoters in membrane filtration was studied. This study showed that it is possible to deform an originally flat membrane to a corrugated shape without damaging it. In hyperfiltration experiments using corrugated cellulose acetate membranes it was found that the corrugations improve mass transfer, provided they are not too close together. At a given value of the mass-transfer coefficient, the presence of corrugations can lead to lower energy consumption in hyperfiltration than possible with flat membranes.
