Abstract
Abstract
The article deals with optimising the design parameters of wastewater production and specific pollution production in wastewater treatment plants up to 2,000 PE. The values of design parameters for the WWTP calculation are laid down in the legislation (ČSN 75 6401 and ČSN 75 6402) recommending their use with a potential reduction in the pollution of up to 50% according to the size of the municipality. Determination of the pollution reduction is no longer defined in standards and design values for different drainage systems are not defined, either. The design values for WWTP calculations should be based on realistic measurements covering at least the past three years. The objective of this article is to determine more precise design values applicable to WWTP calculations and different drainage systems on the basis of statistical evaluation of individual water quality indicator analyses.
