Abstract

1513406 Cleaning membrane surfaces UOP INC 24 Sept 1975 39082/75 Heading B1X A method of cleaning the surface of a membrane used in a separation process and having material accumulated on its surface comprises repeatedly driving liquid droplets across the surface propelled by a gas stream at superatmospheric pressure to effect removal of the material without damage to the surface.
