Improved Operating Efficiency with the NH4D sc ISE Ammonium Probe

The idyllic scene in the photo above is deceptive, as the tranquil oxidation ditch of the Rommerskirchen-Villau sewage treatment plant (PE 5,000) could be more sparing with its oxygen transfer. The plant operator, the Erftverband (a wastewater disposer with its headquarters in Bergheim), has therefore decided to improve its operating efficiency. Many other small and medium-sized plants are in a similar situation. Without adequate modern instrumentation, they have very little insight into their treatment processes. The development of more affordable and more simply designed process meters, which require no sample preparation, will make energy savings.
