IHE Delft Alumni & Partners Online Seminar by Prof. Marcos von Sperling

Online seminar: "Simple sewage treatment processes in low and middle-income countries"

  • 27 Jul 2021
  • 11:45 - 12:45
Delft, The Netherlands (CET time zone)

IHE Delft Alumni & Partners Online Seminars are designed as a means of providing lifelong learning to the Institute Alumni community and Partners. Since the topics will be of interest to a broader audience, they are open to all interested persons. The Online Seminars are like interactive lectures transmitted over the web, with a duration of one hour including time for discussion. The seminar is organized in collaboration with IHE Delft partner TheWaterChannel.


The presentation will give an overview of simple sewage treatment processes that can be applied in warm-climate regions and also in low-and-middle-income countries. The processes covered are stabilization ponds, constructed wetlands, overland flow, UASB reactors and post-treatment of anaerobic effluents. A comparison is made between their typical performances and characteristics, including their capacity to remove the major macro-pollutants of interest in domestic wastewater: organic matter, nitrogen, phosphorus and pathogens.
