Ammonia
As stated in a WHO report on drinking water: “The presence of elevated ammonia levels in raw water may interfere with the operation of manganese-removal filters because too much oxygen is consumed by nitrification, resulting in mouldy, earthy-tasting water. The presence of the ammonium cation in raw water may result in drinking-water containing nitrite as the result of catalytic action or the accidental colonization of filters by ammonium-oxidizing bacteria” The analysis of Ammonia with ALERTs can be done either colorimetrically or with ion selective electrodes, depending on the desired detection range and limits. Manganese and nitrite mentioned above can also be measured with an ALERT analyzer.
Phenol
Many organic compounds are hazardous to treatment works, but a low cost analyser installed on site can enable the process to operate without failure. The Alert Phenol analyser is one of many specifically designed analysers in the range.
TOC/COD
These analysers are probably the most common instrument to be found at a waste treatment plant. With the ability to offer traditional digestion systems or High temperature analysers, Metrohm can supply an analyser for all requirements(Legislation or Monitoring)
