A Model 2000 Process Analyzer (DCA), with both DO and SS sensors, was installed in a standard aeration basin  of a WWTP in South Louisiana.   The results of  the test show that a significant cost saving could be realized with better blower control.  See the test results in DO SS TREND.PDF.  (35KB)

InsiteIG has completed a successful test of our optical dissolved oxygen system in an anaerobic selector. The site was located in the Charlotte, NC area. Typical DO levels were between .03 and .08. The system did not require calibration or maintenance during the test.
