Abstract:
In combination with a cleansing system for separation of waste from liquid thereby cleansed by passage through a membrane, a diverter valve, analyzer means connected to the diverter valve for control thereof to alternatively discharge the cleansed liquid therefrom or store the cleansed liquid for reprocessing by the cleansing system; and monitoring means through which the cleansed liquid is delivered to the diverter valve from the cleansing system for determining performance integrity of the membrane comprising: an enclosure through which flow of the cleansed liquid is conducted exclusively to the diverter valve; means sealingly confining a body of ambient atmospheric air having light energy therein within the enclosure for contact with a surface on the cleansed liquid during said flow thereof through the enclosure; and sensor means for optically detecting the light energy within said body of air in the enclosure after absorption by the cleansed liquid through said surface thereon to furnish signal data to the analyzer means from which the performance integrity of the membrane is determined.
