Abstract | Product quality deterioration, caused by poor wet end control and the resulting build up of dissolved inorganic and organic contaminants, has hampered achieving complete water reuse in paper manufacturing. By using pulp-derived dissolved organic material, the study makes use of a dynamic retention/drainage jar to show the negative effects of these compounds on retention. Alum control is investigated as a means of improving retention in closed whitewater systems through literature review and experimentation. A retention control strategy for total water reuse is proposed. It is based on the measurement and manipulation of alum concentrations in the stock chest; in low shear systems where no polymer is used, to control the electrokinetic balance for proper coagulation, and in high shear systems where polymers are used to eliminate the negative effects due to alum/polymer interactions. |
