Probabilistic WWTP Design and Upgrade in a Water Quality Based Regulation Context
Abstract:Process choice and dimensioning of WWTPs is a particularly sensitive step to cost-efficiently comply with regulatory standards. This step accounts only for a small fraction of the upfront costs, but it can lead to substantial savings.
This paper illustrates the results of a systematic methodology to evaluate system design/upgrade options with regard to both effluent quality and receiving water quality. In contrast to conventional practice, the presented approach allows choosing the most appropriate trade-off between cost of measures and effluent quality, and to assess the reliability of a process layout by means of uncertainty analysis. It is therefore a flexible instrument to cope with the flexibility and complexity of integrated water management regulations.
