Cofie, Olufunke O.Agbottah, S.Strauss, M.Esseku, H.Montangero, A.Awuah, E.Kone, D.[Solid-liquid separation of faecal sludge using drying beds in Ghana: implications for nutrient recycling in urban agriculture]Solid-liquid separation of faecal sludge using drying beds in Ghana: implications for nutrient recycling in urban agriculture

A shortage of available labour early in the growing season, when effort is directed to the weeding of cereal crops, appeared to be a primary constraint to increased forage cropping by smallholder farmers in the semi-arid zone of central Mali. In experiments with millet, the labour requirement for...


Bartholomew, P.W.Ly, R.Kone, D.Traoré, S.F.Sissoko, K.[Forage production for smallholder farmers in a rainfed millet cropping system in central Mali]Forage production for smallholder farmers in a rainfed millet cropping system in central Mali

This paper presents the potentials and performance of combined treatment of faecal sludge (FS) and municipal solid waste (SW) through co-composting. The objectives were to investigate the appropriate SW type, SW/FS mixing ratio and the effect of turning frequency on compost maturity and quality. ...


Cofie, Olufunke O.Kone, D.Rothenberger, S.Moser, D.Zubruegg, C.[Co-composting of faecal sludge and organic solid waste for agriculture: process dynamics]Co-composting of faecal sludge and organic solid waste for agriculture: process dynamics

This study investigates helminth eggs removal and inactivation efficiency in a treatment process combining faecal sludge (FS) dewatering and subsequent co-composting with organic solid waste as a function of windrow turning frequency. Fresh public toilet sludge and septage mixed at a 1:2 ratio we...


Kone, D.Cofie, Olufunke O.Zurbrugg, C.Gallizzi, K.Moser, D.Drescher, S.Strauss, M.[Helminth eggs inactivation efficiency by faecal sludge dewatering and co-composting in tropical climates]Helminth eggs inactivation efficiency by faecal sludge dewatering and co-composting in tropical climates

This research is aimed at investigating the effect of different particle sizes of sand for the dewatering of faecal sludge with respect to the dewatering time, contaminant load in the percolate, rate of clogging and quantity of biosolids produced. Three filter media FM1, FM2 and FM3 were used to ...


Kuffour, A.R.Awuah, E.Anyemedu, F.O.K.Strauss, M.Kone, D.Cofie, Olufunke O.[Effect of using different particle sizes of sand as filter media for dewatering faecal sludge]Effect of using different particle sizes of sand as filter media for dewatering faecal sludge
