چکیده

Coagulation-flocculation is a process often used in the industrial wastewater treatment. to replace the use of the chemical products in this kind of process and eliminate their downside effects on the water disposal process,a bio-flocculent extracted from the racket of opuntia ficus indica,cactus juice

has been utilized. Two types of wastewater have been used in the experiments: A synthetic solution of chromium sulfate at 100ppm or 500ppm and a real effluent coming from a tannery at 90ppm or 900ppm. The results obtained show that the flocculation is rapid in the range of pH 7-9. Neutralization and lime's coagulation followed by cactus juice flocculation greatly reduce metal charge values
