ABSTRACT
For the importance of floc size (A) in industrial applications, and thatneeded in retention of fines in papermaking, the objective of this workhas been concentrated on the process factors and their role to affect theflocculation process parameters. In this work, in fines flocculationusing the cofactor (CF) polyethylene oxide (PEO) retention aid, wehave analyzed the effects of the following process factors on the flocsize: the cofactor concentration (C) , the fines consistency ( ) fn C , andthe floc shearing after production ( ) t G . To maintain the fines floc atthe required size and less cost, we have proposed a methodology byusing the values of the effective process factors that lead to the required floc size. In casesthat larger flocs are resulted, the methodology proposed to shear the resulted flocs that reducethe larger sizes into the required one. This methodology can be used in flocculation processesin industry as in fines flocculation.
