摘要: Polyphenolic substances such as food dyes, tannins, fruit juices and wine colorings are removed from a solution by adsorption onto a regeneratable adsorbent polyamide of extended surface and controlled porosity. The surface chemistry of the polyamide may be modified by a glutaraldehyde/resorcinol treatment. The polyphenolic substances are recovered by elution with water or other protonic solvent.

摘要: A concentrator for concentrating the fine solids of a liquid feed suspension has a shell within which there is a bundle of microporous fibers. Pressurized feed suspension is introduced through an inlet and passes over the external walls of the fibers with the clarified liquid being drawn from the lumens of the fibers and the concentrated feed being discharged through an outlet. The solids retained within the shell are removed by first applying a pressurized liquid and then applying a gas at a pressure sufficient to ensure that the gas will pass through the larger pores of the fibrs to remove the solids from the shell through the outlet to an external collection point. The fibers are enclosed within a variable volume diaphragm located within a diaphragm holder by spaced plugs. The volume of the diaphragm is altered by varying the pressure of a fluid introduced through the inlet to the space between the diaphragm and the diaphragm holder.

摘要: A reversed phase analogue of at least part of a first membrane having substantially interconnected pores is formed by first filling at least some of the pores of the first membrane with a fluid that will form the analogue membrane and then forming the analogue membrane in the pores of the first membrane. The first membrane is then removed from the analogue membrane. The structure of the analogue membrane is of different morphology from that of the first membrane and the reversed phase nature arises because it is the pores of the first membrane which lead to the formation of the walls of the reversed phase membrane and it is the walls of the pores of the first membrane which lead to the formation of the pores of the reverse phase membrane.

摘要: Water is separated from an oil emulsion containing a surface active agent by passing the emulsion through a polymeric porous membrane cross-flow ultra-filter. Either the oil emulsion feedstock or the membrane is treated with a hydrophilic colloid so that the effective pore size of the composite membrane so formed by the colloid will be reduced as the surface tension falls in the presence of the surface active agent in the oil emulsion. The hydrophilic colloid is selected according to the chemical ionic classification of the surface active agent.

摘要: A method of making a porous polymeric material by heating a mixture of a thermoplastic polymer and a cationic or non-ionic surfactant having a hydrophilic-lipophilic balance range of 4.0 to 6.0 to a temperature and for a time sufficient for the polymer and surfactant to mutually dissolve. The mixture is then cooled to a temperature so that non-equilibrium liquid-liquid phase separation takes place to form a bi-continuous matrix of the polymer and surfactant so that the polymer and surfactant form two intermingled separate phases of large interfacial surface area. The surfactant is then removed from the polymer. The porous polymeric material produced by the above method has a lacey or filamentous structure consisting of a plurality of polymer strands connected together at spaced apart locations along each strand.
