Aims and objectives
Aim The project aims to explore the advantages
and disadvantages of the catchment based and
real-time-based permitting in an integrated urban
wastewater system.

• Objectives
• Review on the existing permitting policies in
  England and Wales, and other typical
  areas/countries
• Try potential real-time controls on the Benchmark
  case to acquire the relationships between control
  variables/effluent quality/operation cost/GHG
  emission
• Establish the integrated urban wastewater system
  model for a real-life case and conduct the
  dynamic permitting research
• Draft a guideline for the innovative permitting
  approaches
• Write up the degree thesis and the journal and
  conference papers
• Courses, trainings and conferences
