Modeling and optimization of experimental parameters in the treatment of effluents by coagulation-flocculation processes: Methodology of experimental design

Hanane hanane Arroub, Ahmed El Harfi

Abstract


The objective of this study is to determine the optimal conditions of the operational parameters: type of flocculant (chitosan(s) and ferrocryl®8723), dose of flocculant (0.1g/L at 0.5g/L) and pH (6 to 9) in the treatment of hot dip galvanizing effluents using coagulation/flocculation processes. The optimization of these parameters is done by the methodology of experimental design which allowed us to predict the optimal conditions. The concerned results, especially the theoretical operating parameters, allowed us to give a better reduction of the TSS, BOD5 and COD in the optimal conditions namely: the pH of about 9, the type of flocculant is chitosan(s) with a dose of 0.2g/L.
