1.7 ORGANISATION OF THE THESIS
This study documents the performance of the pilot-scale ABR and considers its application in the
treatment of domestic wastewater. Figure 1.4 shows the logical flow of this thesis.

and operation
Chapter 1 introduces low cost sanitation in South Africa and the ABR project. Objectives of the study
and the hypotheses of the research are presented.
Chapter 2 presents an overview of relevant literature including general theory of anaerobic digestion,
anaerobic digester technology, anaerobic digestion of sewage and research into the anaerobic baffled
reactor.
Chapter 3 is the materials and methods chapter of the thesis, and describes the construction of the
pilot-scale ABR, installations at Umbilo and Kingsburgh WWTP, and sampling and analytical
methods used in this study.
Chapter 4 and Chapter 5 present and analyse the results of operation of the pilot-scale ABR at
Umbilo and Kingsburgh WWTP.
Chapter 6 is the central chapter of the thesis in which the findings of the previous two chapters are
considered in terms of what they reveal about design requirements of an ABR for domestic wastewater
treatment. Gaps in the information are identified and mass balance and steady-state models are
employed to supply the missing data, where possible.
Chapter 7 presents the conclusions and recommendations for future research.
