Abstracts
The RAPS method (Rescaled Adjusted Partial Sums) was implemented to analysing input and output indictors of the Čakovec wastewater treatment plant during June, July and August 2015. The paper’s aim was to establish a relation of the precipitation volume and daily mean air temperature with the values of input and output time series related to chemical oxygen demand (COD), 5-day biological oxygen demand (BOD5) and suspended solids at the WWTP. The RAPS method was applied to precipitation volume time series, but was not higly efficient due to large osciallations of precipita¬iton volumes in the observed period. A further analysis was based excluisvely on the comparison of the input and output values of COD, BOD5 and suspended solids with daily mean air temperature. The results show that the input series contain more pronounced subseries in terms of their mean value and the trends of increasing or decreasing values. In comparison with the input subseries, the output subseries do not oscillate in such measure since they are related to wastewater output quality. A visible decrease in indicator outlet values confirms a high quality treatment of input wastewater.
