Humification performance and helminth eggs inactivation in faecal sludge dewatering bed

Résumé

The agronomic potential of wastewaters in general and faecal sludge in particular is now recognized by the scientific community as well as farmers. Indeed, in Dakar these products are used in urban agriculture, with satisfactory results in terms of productivity. At the Faecal Sludge Treatment Plant (FSTP) of Camberene, the gardeners and florists are showing more and more interests for the dried sludge from drying beds. However, these practices of reuse pose environmental and health risks because they facilitate the transmission channels of different forms of pollution. To remedy to this and take more advantage of the agronomic potential of sludge, many treatment options have been tried. These are simple, hygienic, low cost and adapted to climate conditions of developing countries. Vertical Flow Constructed Wetlands (VFCW) are, to date, recognized as capable to reduce faecal sludge pollutant content and transform sludge into a stable humus which can be safely used as agricultural amendments. In this process of transformation, a number of factors are involved in different ways. The overall objective of this study was to evaluate the impact of these factors on the process of humification and the inactivation of helminth eggs. The scientific approach to be adopted will be to shed light on the influence of residual moisture, the nature of plants and the nature of the incoming sludge to develop ideas on how to use VFCW in an optimal way that allow the the production of safe humus.
