Purification technologies have been rapidly evolving lately due to the large number of applications that have been made, both for city and industrial wastewater use. An important direction of evolution is related to the development of monitoring devices for the operation of sewage treatment plants. Applications that tracked performance parameters and quality indicators highlighted optimal exploitation technologies and technologies that ultimately led to increased efficiency and lower costs. In purification, the critical process indicator is "nitrogen"; reducing and framing this indicator within the limits imposed by legislation implying the inclusion of all quality indicators. The development of continuous nitrogen monitoring devices has allowed the purification, nitrification and denitrification processes to be balanced, and the development of appropriate operating and adjustment programs. The control of the ammoniacal and nitrate nitrogen treatment is the best option for optimizing the operation of the treatment plants. In the material are presented the process philosophies and the results obtained from the regulation of the functioning of the nitrogen treatment plants Continuous monitoring and regulation ensures the reduction of impacts on water resources.
