Ecological Systems and Devices Annotation << Back EVALUATION OF STABILITY OF QUALITY PARAMETERS IN DRINKING WATER TREATMENT V.N. Klyachkin, A.D. Bart A methodology for assessing the stability of physicochemical quality indicators in the purifi cation of drinking water has been developed. It is proposed to monitor indicators using statistical management methods used to control technological processes. In this case, standard Shewhart control charts can be used for uncorrelated indicators. The stability of the dependent indicators is estimated using multivariate Hotelling charts. Practical calculations were conducted using the data of the St. Petersburg Vodokanal. Keywords: Physicochemical indicators; statistical methods; Shewhart control charts; multivariate Hotelling chart.
