Area of Science:

  • Environmental Engineering
  • Wastewater Treatment Technology
  • Water Resource Management

Background:

  • The sewer system in Helsingborg, Sweden, underwent significant rehabilitation and the Oresundsverket Wastewater Treatment Plant (WWTP) was reconstructed.
  • The primary goal was to achieve high levels of nitrogen and phosphorus removal.

Purpose of the Study:

  • To apply a holistic approach optimizing corrective measures for improved effects in receiving waters.
  • To evaluate various operation strategies and the impact of introducing Real-Time Control (RTC).
  • To establish stable communication with the SCADA system and generate short-term flow forecasts using a newly installed MOUSE ONLINE system.

Main Methods:

  • Utilized a sewer catchment model to assess different operational strategies.
