Abstract:
The present invention relates to a process for dewatering a slurry comprising microfibrillated cellulose wherein the process comprises the following steps of, providing a slurry comprising microfibrillated cellulose and liquid, subjecting the slurry to an electric field inducing the liquid of the slurry to flow and separating the liquid from the microfibrillated cellulose. The invention also relates to microfibrillated cellulose dewatered according to the process.
