| Abstract |
Two techniques for recovery of filler from fine papermill high ash sludges, screening and wet oxidation, were evaluated for their technical feasibility. The alternative of screening the sludge and using the material passing through the screen as recovered filler was investigated in cooperation with two mills. The screening for recovery of filler was conducted at the mill site. Then the material was shipped to Western Michigan University where selected grades incorporating the recovered filler were manufactured. The grades simulated were found lacking only in brightness by comparison with virgin filler. The wet oxidation alternative was evaluated in a similar manner with a cooperating mill. The wet oxidized recovered fillers only slightly lowered the brightness of the sheet simulated and gave an increase in opacity in exchange. The wet oxidation scheme appears technically feasible. |
