Application of a 2k–p Fractional Experimental Design in Coagulation-Flocculation Processes in the Treatment of Wastewater from a Slaughterhouse

Determining the optimal dose of coagulant required to perform flocculation is critical in most water treatment plants’ planning and operation. This study implemented a 2k–p fractional factorial design experiments identify factors influencing color decrease wastewater from slaughterhouse. The variables assessed were velocity gradient, residence time, primary dosage, chlorine coagulation adjuvant dosage. results indicate that gradient significantly affect samples’ other can be run at low technical-economic level start up plant. allowed reducing number experimental points without affecting minimum information which are significant sample.
