چکیده

Three types of ponds used for treating domestic wastewater in Burkina Faso in Soudano-sahelian climate, were monitored for sludge accumulation. After five and a half years of operation, the rates of sludge accumulation in the ponds were evaluated to 0.02; 0.009 and 0.007 m 3 /capita year respectively for the anaerobic, facultative and maturation ponds. The corresponding rates of accumulation in dry weight (dw) per person per year were calculated to 1.3, 0.43 and 0.26 kg dw/capita year respectively in anaerobic, facultative and maturation ponds. A coefficient of high biodegradability of sludge was found in the anaerobic pond.
