ABSTRACT:
The washing efficiency of removal of cooking and bleaching chemicals from cellulose paper pulp on horizontal belt washing filters is improved by disrupting the filter mat adjacent the belt intermediately of soft, displacement wash liquor applications to the filter mat topside. The objective may be achieved by directing a line of low volume, high pressure jets of filtrate or wash liquor against the belt underside. Alternatively, sonicly vibrated foils extended transversely of and adjacent to the belt are effective to disrupt the filler mat pursuant to the invention objective.
