<p>A method for production of a micro-porous membrane for filtration plants, whereby finely distributed particles are mixed and aligned in a plastics material or a preliminary plastics material product and are insoluble therein, the particles are then dissolved out after reaching the final mould position; said insoluble particles mixed into the plastics material or preliminary plastics material product being aligned in a liquid state in the pores of a coarse pored support membrane at right angles to the membrane surface.</p> |
