Abstract
A method and system for early detection of biofouling utilizing a fluorescence based extracellular enzyme activity assay is disclosed. The method provides a means for early detection of biofouling on membranes used in flow-through membrane filtration systems for with a feed water flow, such as waste water of water for desalination. Also disclosed is an at-line sensor utilizing the fluorescence based extracellular enzyme activity assay that is positioned in the membrane filtration system for detection of biofouling.
