摘要
The reduction of energy consumption in Waste Water Treatment Plants (WWTPs) is a challenge for the scientific community and for the public authorities. A source of excessive energy cost is the mismatching between operational and design inflow (i.e. capacity utilization): this issue is very relevant above all in areas with high demographic seasonality. Consequently, it is really important to have operational decision criteria to evaluate the impact of a low capacity utilization on energy consumption. In order to provide the scientific community and the plant managers with an adequate criterion, we propose a user-friendly methodology to identify critical conditions of capacity utilization. The novelty of this paper relies upon the combination of a parametric approach and statistical analysis. This methodology has a practical value for plant managers and designers that can improve their comprehension of plant performances by using a user-friendly decision-making criterion.
