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.

摘要： Polyphenolic substances such as food dyes, tannins, fruit juices and wine colourings 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： Pores that are smaller than or larger than a predetermined range of pore sizes in a porous membrane barrier are blocked with a controlled porosity blocking agent. The pores are first filled with a liquid so as to remove any air therein and then subjected to a transmembrane gas blow at a pressure which will clear the larger pores of the liquid. The larger gas filled pores or the smaller liquid filled pores are then blocked by a blocking agent using a polymer-forming chemical reaction, a precipitate-forming chemical reaction or the physical deposition of solids.

The method comprises passing the feedstream through a filter (5) having known characteristics; determining the change in resistance to flow of the feedstream across the filter, either continuously or over a number of time intervals and from this data, calculating a feed fouling index (FFI) representative of the fouling characteristics of the feedstream with respect to the filter. A method and apparatus for monitoring the operation of a filtration system is also disclosed the method comprising sampling system parameter values at selected locations within the filtration system at a predetermined sampling rate; generating a parameter profile characteristic from the sampled parameter values at predetermined intervals of time; and analysing the parameter profile characteristic to determine correct operation of the filtration system. A further method and apparatus of monitoring and controlling a filtering system based on backwash efficiency is also disclosed, the method comprising determining resistance values of filtering elements used in the filtering system at predetermined times during the backwash cycle of the system by monitoring a number of operating parameters of the system; calculating a backwash efficiency value representative of the efficiency of the backwash cycle of the filtering system using the resistance values determined; and controlling the operation of the filtering system in dependence on the value of the backwash efficiency calculated.

摘要： A filtration system for treating an emulsion containing water, an oil or a fat, an emulsifying agent and insoluble solid material (such as a maritime oil emulsion containing an anionic detergent and the solid, greasy calcium salt of the detergent) has a first hydrophobic microfilter (126) and a second hydrophobic microfilter (147). Both microfilters (126, 147) have a plurality of hollow porous fibres as the separating medium with the feed to the first filter (126) being applied to the outside of the fibres and the feed to the second filter (which is the permeate from the first filter) being applied down the lumens of the fibres. The first filter (126) removes the solid material and the second filter separates the oil or fat from the solid-free emulsion.

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 process for maintaining a high rate of mass transfer of nutrients contained in a liquid feed stream to a biofilm of microorganisms supported on a bed of particulate matter. The microorganisms in the biofilm are subjected to a continuous, uniform flow of the liquid feed stream and a countercurrent flow of respiratory air so as to support biofilm growth. The bed is periodically pulsed with air at a pressure sufficient to shed microorganisms from the biofilm and at intervals sufficient to avoid preferential channelling of the liquid feed stream through the bed and/or to disrupt and rearrange the bed of particulate matter.
