Abstract

A process for the production of paper by mixing an aqueous phase comprising white water with cellulose containing fibres, and optinal fillers, in a mixing stage to form an aqueous suspension, draining the suspension in the presence of a drainage or retention aid to form a fibre containing sheet or web and white water, and recirculating at least part of the white water to the mixing stage, whereby at least part of the white water is subjected to electrodialysis before the mixing stage.
