Abstract: A method and/or a composition relates to cleaning and reprocessing a hemodialysis filtration membrane assembly that employs polyvinylpyrrolidone-containing membranes. The method includes the step (1-6) of treating the assembly with an aqueous mixture or a gas- liquid mixture having an inorganic base and from 100 to 1,000ppm of a hypochlorite salt, wherein the mixture has a pH between about 12.0 and about 12.5, an oxidation reduction potential of less than 0.5 volts, a temperature of 40° to 55°C and wherein the mole % of hypochlorous acid, HOC1, relative to the sum of hypochlorous acid plus hypochlorite anion, - OC1, is less than 0.004%. The composition may be used in such a method.

Abstract: An apparatus and method for cleaning passageways and the like with a two-phase mixture of gas under pressure and an aqueous cleaning solution. The two-phase cleaning mixture is generated in a module and is passed out of the module at a predetermined rate that determines droplet size, velocity and droplet density at the pipeline surface to be cleaned. The droplets impact the walls of the passageway to be cleaned, thereby fragmenting, eroding and removing contaminants in said passageway. These are then flushed out of the passageway by the two-phase flow. The flow of cleaning solution can be steady or pulsed. The apparatus and process include a cleaning-place system that is useful in food, beverage, pharmaceutical and similar process industries.

Abstract: Hollow porous fibers (12) containing adhered contaminants are cleaned to remove the contaminants by backflushing a liquid to fill the pores, and adding a flow of gas so as to form a two-phase mixture of gas and bubbles of liquid that can scrub the fibers, looseing the contaminants and allowing them to be flushed from the hollow fibers (12).
