Abstract:
When evaluate consequences of a wastewater treatment (WWT) system failure, by using a probabilistic analytical method of
risk assessment, derivation of the so-called limit state functions (LSF) are necessary. For the case study of an accidental pollutant
discharge from a municipal WWT-plant, the LSF have been accurately evaluated by simulating the contaminant fate and transport in a
control section of the riverine pathway by using a diffusion model with accounting for pollutant biodegradation.
