This paper deals the possibilities of eliminating or separation of ammonium shares from technological water from plants; where a secondary method of flue gas denitrification (SCR, SNCR) is introduced. The necessity of ammonium shares elimination arose after introduction of emission cap, which have been tightened since January 2015. The denitrification technologies were installed on devices that did not comply with the new limits. The description of combustion processes, as a fluid, and high temperature combustion of solid fuels, mechanisms of emissions and their reduction options is here introduced. The contents of the ammoniacal nitrogen in technological waters used in electricity and heating facilities to transport, or from which are separated by solid products of some processes such as desulphurization is discussed. Some options of the ammonium salts removal from technological waters are also discussed. The obtained experimental results showed an appropriate method of determination of ammoniacal nitrogen, and the possibilities of its elimination by conversion to insoluble compound. Last but not least, the work deals with the real possibilities of their application in practice.
