Impedence measurements of bipoling in seawater condensers: an update

Abstract

Electrode Impedance Spectroscopy (EIS) is a new technology presently being investigated for its usefulness in measuring biofouling in seawater cooled power plants. EIS is based on the hypothesis that biofouling can be characterized by observing its steady state response to a small amplitude sinusoidal perturbing potential imposed on the biofilm material. From the change in phase and amplitude of the response signal a real-time characterization of the biofilm can be determined.
