About this course

This course will focus on basic technologies for the treatment of urban sewage. Unit processes involved in the treatment chain will be described as well as the physical, chemical and biological processes involved. There will be an emphasis on water quality and the functionality of each unit process within the treatment chain. After the course one should be able to recognize the process units, describe their function and make simple design calculations on urban sewage treatment plants.

The course consists of 6 modules:

  1. Sewage treatment plant overview. In this module you will learn what major pollutants are present in the sewage and why we need to treat sewage prior to discharge to surface waters. The functional units will be briefly discussed.
  2. Primary treatment. In this module you learn how coarse material, sand & grit are removed from the sewage and how to design primary clarification tanks.
  3. Biological treatment. In this module you learn the basics of the carbon, nitrogen and phosphorous cycle and how biological processes are used to treat the main pollutants of concern.
  4. Activated sludge process. In this module you learn the design principles of conventional activated sludge processes including the secondary clarifiers and aeration demand of aeration tanks.
  5. Nitrogen and phosphorus removal. In this module you learn the principles of biological nitrogen removal as well as phosphorus removal by biological and/or chemical means.
  6. Sludge treatment. In this module you will the design principles of sludge thickeners, digesters and dewatering facilities for the concentration and stabilisation of excess sewage sludge. Potentials for energy recovery via the produced biogas will be discussed as well as the direct anaerobic treatment of urban sewage in UASB reactors when climate conditions allow.

This course in combination with the courses “Introduction to Water and Climate” and “Introduction to Drinking Water Treatment” forms the Water XSeries, by DelftX.

What you’ll learn

By the end of this course you will be able to:

  • Identify personal and performance competencies for project management
  • Build a plan for developing required project management competencies
  • Analyze how team dynamics and culture can influence a project
  • Link organizational change management to customer service and delivery readiness
  • Comprehend strategies for managing distributed team projects

Meet Your Instructors

Jules van Lier

Professor, Sanitary Engineering at Delft University of Technology
Jules van Lier is full professor of Environmental Engineering and Wastewater Treatment at the Sanitary Engineering Section of Delft University of Technology and has a 1 day per week posted position at the Unesco-IHE Institute for Water Education, also in Delft Jules van Lier accomplished his PhD on Thermophilic Anaerobic Wastewater Treatment under the supervision of Prof. Gatze Lettinga (1995) at Wageningen University. Throughout his career he has been involved as a senior researcher / project manager in various (inter)national research projects, working on cost-effective water treatment for resource recovery (water, nutrients, biogas, elements). His research projects are focused on closing water cycles in industries and sewage water recovery for irrigated agriculture. The further development of anaerobic treatment technology is his prime focus. In addition to university work he is an Executive Board Member and Scientific Advisor to the LeAF Foundation; regional representative for Western Europe Anaerobic Digestion Specialist group of the International Water Association (IWA); editor of scientific journals (e.g Water Science Technology and Advances in Environmental Research and Development); member of the Paques Technological Advisory Commission; and member of the Advisory Board of World-Waternet, Amsterdam.

Merle de Kreuk

Associate Professor, Sanitary Engineering at Delft University of Technology
Merle de Kreuk is a wastewater Associate Professor at the Sanitary Engineering department of the Delft University of Technology. Her research focus is on (municipal and industrial) wastewater treatment systems and anaerobic processes, aiming to link the world of Biotechnology to the Civil Engineering, as well as fundamental research to industrial applications. Her main research topics are hydrolysis processes in anaerobic treatment and granule formation and deterioration. Merle’s PhD and Post-Doc research involved the development of aerobic granular sludge technology and up scaling the technology from a three litre lab scale reactor to the full scale Nereda® process®. The first application of aerobic granular sludge technology in the Netherlands was opened in May 2012, and currently many more installations are being built, due to its compactness, low energy use and good effluent characteristics. Her previous work experience also involved the position of water treatment technology innovator at Water authority Hollandse Delta on projects such as the Energy Factory in which 14 water authorities cooperated to develop an energy producing sewage treatment plant.
