ABSTRACT:

The possibility of using a plant material, prickly pear cactus, Opuntia ficus Indica, juice (OFIJ), for conditioning the Beni-messous wastewater treatment plant sludge was examined. Optimum dosage of OFIJ was found to be 0.4gkg-1 of dry matter. The residual turbidity, the dryness of filtration cake and the specific resistance of filtration were found to be 2.5 NTU, 24% and 0.13×1012 mkg-1 respectively. The results obtained with OFIJ were compared to those obtained with polyelectrolytes: Chimfloc C4346, a cationic polymer, Sedipur NF 102, a non-ionic polymer and Sedipu AF 400, an annon-ionic polymer, and inorganic conditioners, FeCl3 and Al2(SO4)3. The optimum dosages of those conditioners were found to be 0.4gkg-1 for OFIJ,
