ABSTRACT:
A method for forming filtration members using an electric potential to control the migration of electrically charged particles and hence to control the formation of a membrane layer on a substrate. In one embodiment, electrophoresis and electrodialysis processes are used to control the migration of sol particles and the deposition of the sol particles to provide a desired pore size associated with the membrane layer. In another embodiment, the substrate pores are impregnated with a reagent and, subsequently, electrophoresis and "reverse" electrophoresis processes are utilized to control the diffusion of ions in connection with the formation of the membrane layer.
