Abstract: Process for purifying a slurry comprising cellulose by salt/ion depletion and/or free sugar depletion. The process comprises the following steps of providing a slurry comprising cellulose and liquid, subjecting the slurry to a first application of an electric field inducing the liquid of the slurry to flow, separating the liquid from the cellulose thus obtaining a liquid depleted slurry, adding a washing liquid to the liquid depleted slurry, subjecting the liquid depleted slurry to a second application of an electric field inducing the washing liquid of the slurry to flow and separating the washing liquid from the cellulose, thus obtaining a purified cellulose.
