Abstract


The system of automatic chemical solution metering, used in urban water and wastewater treatment plants, is considered in the article. A functional diagram is proposed; simulation of Bessel filter of the third kind and Butterworth filters of the second and third kinds to rectify the signal is performed.

Keywords


automatic metering; noise; optimal filter
