Abstract

A papermaking process which includes preparing a papermaking stock and delivering that stock to the headbox of a papermachine for deliver onto a machine wire, draining the stock on the wire and processing the backwater or white water thus obtained to generate two fractions one of which fractions has a higher solids content than the other fraction, delivering the fraction having a high solids content for use in preparing papermaking stock and discharging the fraction having a low solids content to waste or for re-use as process water in another part of the process. <IMAGE>
