Maximum operational reliability and degradation efficiency are assured in Rhede (NRW, Germany) by a combination of a nitrate probe and an ammonium electrode. Together they regulate nitrogen elimination in the intermittently aerated B stage of an A-B plant. The sewage treatment plant has to deal with industrial wastewater, and therefore has a high-load.
