  • How has wastewater treatment changed in the Netherlands?
  • Wastewater treatment in the Netherlands has improved enormously in the past decades. Almost all wastewater is treated before it is discharged into the surface water. The discharges of industrial wastewater are greatly reduced as well.
  • How to optimize the operation of a wastewater treatment plant (WWTP)?
  • In this study, an approach for optimal operation of the WWTP has been presented considering the quantitative and qualitative variables of influent. In the proposed method, first, the simulation model of WWTP is developed and calibrated using the recorded data of its influent and effluent characteristics as well as operation conditions.
  • How does water management work in the Netherlands?
  • Water management therefore involves much more than building dykes and windmills. In the Netherlands approximately 11.000 employees work 24/7 to keep the feet of the Dutch inhabitants dry and to make sure they are supplied with clean and safe water.
  • Can a numerical optimization algorithm improve the cost effectiveness of wastewater treatment?
  • This research was unique in the coupling of an external biological simulation model with a numerical optimization algorithm to minimize total costs including those related to design, operation, and performance. This approach has the potential to significantly improve the cost effectiveness of wastewater treatment design and operation in practice.
