This course introduces the participants to the concept, application and design of anaerobic reactors and a number of natural systems for wastewater treatment.
The syllabus includes the following subjects: rationale of applying natural systems for wastewater management; role of anaerobic pre-treatment in sanitation strategies; anaerobic reactor technology; nutrient cycles; waste stabilisation ponds; fish aquaculture; macrophyte ponds; constructed wetlands; land applications; technology selection; World Health Organisation and Food & Agricultural Organisation guidelines, development of appropriate cropping patterns, crop selection, irrigation technology and nutrient demand; and matching irrigation water supply and demand.
Upon completion, the participant should be able to:
- describe the physical, chemical and microbiological processes occurring in
- anaerobic reactors and a number of natural systems
- critically reflect on the current sanitation systems encountered in many urban areas and to indicate ways to improve this situation in a sustainable manner;
- evaluate the possibilities for closing cycles of energy, water and nutrients
- evaluate the feasibility of the application of the technologies studied in this module in urban settings in the developing world
- carry out preliminary process design of treatment and reuse systems to assess the needs for capital, land, equipment and operation and maintenance
