Abstract

Method for removing impurities from a liquid, which comprises precoating a filter mule by depositing on said filter mesh a first layer of ion exchange resin powder particles, then depositing a second layer of polyacrylonitrile fibers on said first layer of resin exchange particles ion, and passing said liquid through said first and second layers and said filter mesh.
