Monitoring treatment plants automatically

Use of “wipe-clean” luminescence dissolved oxygen probes is ideal in pre-aeration basins where oil/grease, hydrogen sulfide, and chemicals foul membrane-type sensors, and in aeration basins prone to slime. Photo: T.Z. Osborne WWTP, Greensboro, N.C.

With universal, multiple-input controllers, wastewater treatment plant operators can install a variety of digital sensors in plug-and-play connection, reducing the instrumentation costs, installation labor, operator training, and maintenance efforts that can limit the payback of other continuous analysis systems.

With this probe, operators see significantly less probe maintenance and calibration. Source: Hach Co.
