Float Holders Significantly Reduce Dissolved Oxygen Sensor Maintenance Workload (at Oxidation Ditch Type Sewage Treatment Plants)

Download Whitepaper
The detectors used to perform dissolved oxygen (DO) measurement in oxidation ditch type sewage treatment plants tend to become dirty quickly and require frequent cleaning. It has been difficult to remedy this problem inexpensively. One solution that significantly reduces the sensor maintenance workload is the use of float holders. A field test using float holders on the detectors in the FLXA402 dissolved oxygen analyzer system has demonstrated that the sensors could be kept free of heavy dirt accumulation, eliminating the need for maintenance and enabling continuous measurement for long periods of time.
