The main Factors in the Treatment of Faecal sludge: A mini review

The aim this research was to present an overview of the key aspects of faecal sludge treatment based on the research available over the last 5 and 10 years, in line with the context of developing countries on the African continent. This research is a literature review. The publications were collected mainly from the web databases of the ‘reaserch gate’, ‘google scholar’ and ‘academia.edu’ platforms, where articles, manuals, technical reports or other relevant documents were extracted. The variables or key factors to be considered in the treatment of faecal sludge that have been identified through this research are far from exhaustive. The few that have been retained have been classified as technical, environmental, economic and social factors. Research published on the subject over the last 5 and 10 years is a relevant source of information. The variables or key factors encountered have been grouped into 4 main categories: technical, environmental, economic and social. If faecal sludge treatment is to be sustainable, appropriate technology is needed, based on a sound knowledge of environmental requirements and a mastery of economic and financial aspects, without neglecting the needs and role of stakeholders.
