| titleOfInvention | Method of production of a micro-porous membrane for filtration plants |
| abstract | ABSTRACT OF THE DISCLOSURE A method for production of a micro-porous membrane comprising the steps of: mixing a quantity of finely divided particulate material into a fluid, membrane-forming polymer material; said particulate material being insoluble in said polymer material; forming the particle-containing fluid polymer material into a thin layer and aligning the particles in said layer sub-stantially normal to the surface of said layer while said polymer material is in the fluid state; solidifying said layer containing the aligned particles to form an aligned particle containing membrane; and extracting particles from the aligned particle contain-ing membrane without destroying the membrane to produce a micro-porous membrane having aligned pores substantially normal to the surface of the membrane. These membranes find use in ultra-filtration, dialysis, and reverse osmosis procedures. Such membranes do not suffer from the manufacturing difficulties en-countered with known membranes, such as control of pore size. |
