Abstract

A device for in situ cleaning a fouled membrane of a sensor disposed in an aqueous process solution includes a first electrolysis electrode disposed in the process solution immediately adjacent the membrane, a second electrolysis electrode disposed in the process solution and spaced apart from the first electrolysis electrode, and a controllable power source for passing a current between said first and second electrodes. The current produces a heavy concentration of ions at a surface of the fouled membrane. The polarity of the current is selectable to produce negative or positive ions for reacting to decompose deposited salts, or to scrub contaminates from the membrane surface.
