Abstract: Using distilled water and/or aqueous polyacrylamide solutions, the mechanism of the displacement washing of unbleached kraft pulp was investigated. The step change technique has been employed in the investigation of displacement of black liquor. To characterize the displacement of black liquor, the washing curves as well as wash yield at the wash liquor ratio equal to unity were determined. The results obtained for pure wash water were compared with those for polyacrylamide solutions.
