To improve the planning of maintenance of the drift eliminators of its counter flow natural draft cooling towers, EDF decided to run two campaigns of tests: the first one focused on the effect of the mechanical deterioration of drift eliminators. Because of fouling issues due to the use of untreated raw water as make up, the second test was applied on eliminators with a layer of about 1.5 millimeter of fouling. For both tests, the CTI ATC-140 was used with its former recommendations for analyzing the samples: drift measurement using conductivity methodology.
