Population growth, urbanization
and economic activities have resulted in an increase
in wastewater volumes across the world, with
this trend expected to continue (Sato et al. 2013),
including in Africa, which has experienced the
highest population growth rate in the world of
2.51 per cent during the period 2000–2015 (United
Nations Department of Economic and Social Affairs
[UNDESA] 2019). The
wastewater streams responsible for the bulk of water
pollution in Africa can be classified as municipal
wastewater, agricultural wastewater, industrial
wastewater, urban storm water run-off and hospital
wastewater (Wang et al. 2014; Laffite 2016).
