Abstract
Method for preparing a membrane from fibril cellulose comprises - supplying fibril cellulose dispersion on a filter layer, - draining liquid from a fibril cellulose dispersion by the effect of reduced pressure through the filter layer that is impermeable to fibrils of the fibril cellulose but permeable to the liquid to form a membrane sheet on the filter fabric, - applying heat on the opposite side of the membrane sheet to the membrane sheet while continuing draining of the liquid through the filter layer by pressure difference over the filter layer, and - removing the membrane sheet from the filter layer as a freestanding membrane.
