Integrated operation of sewer system and WWTP by simulation-based control of the WWTP inflow

Abstract

In recent years numerical modelling became a standard procedure to optimise urban wastewater systems design and operation by integration. For dynamic control of the wastewater teatment plant (WWTP) inflow, a model-based predictive concept is introduced aiming at improving the receiving water quality. An on-line simulator running parallel to the real WWTP operation reflects the actual state of operation and provides this model information to a prognosis tool which determines the best option for the WWTP inflow. The investigations showed that it is possible to reduce the NH4-N peak concentrations in the receiving water by dynamic WWTP inflow control based on predictive scenario analysis.

Hybrid water treatment cost prediction model for raw water intake optimization

“…For example, McCorquodale et al (2005) used physical modeling to investigate the optimization of the hydraulic conditions of a high-purity oxygen-activated sludge. Also, Seggelke et al (2005) optimized the dynamic control of a treatment plant inflow by using an online simulator running parallel to the real WWTP operation; this provided model information to a prognosis tool which determines the best inflow options.…”

“…Günümüzde ise evsel atıksu arıtma tesislerinin modellenmesi, birçok farklı amaç için kullanılmaktadır. Örneğin; Seggelke ve arkadaşları [8], evsel atıksu arıtma tesisinin modellenmesi kapsamına aşırı yağış koşullarının etkisini incelemiştir. Dinamik modelleme çalışmalarında yaşam döngüsü değerlendirmesi entegrasyonu ile evsel atıksuların nütrient geri kazanım potansiyeli tahmin edilebilmektedir [9].…”
