    Abstract: Filtration processes, especially for water filtration wherein a liquid permeates an asymmetric polymer membrane, are effectively carried out using membranes equipped within organic particles of zinc oxide, or a composite comprising one oxide selected from zinc oxide, aluminum oxide, titanium oxide, silicium oxide, zirconium oxide, and a metal and/or further metal oxide. These particles are largely removed by cleaning operations using chemically enhanced backwash. The processes show improved permeate flux, improved membrane stability, and permit reduced maintenance intervals of filter modules.

    Abstract: The present invention relates to a method for concentrating aqueous solutions of human milk oligosaccharides, in which an aqueous solution comprising at least one human milk oligosaccharide is subjected to a reverse osmosis process by means of a reverse osmosis membrane and is thereby concentrated to a final osmotic pressure of at least 70 bar measured with a freezing point osmometer. Moreover, the present invention refers to an according use of a reverse osmosis membrane, a corresponding reverse osmosis system containing such a membrane and a spray-dried HMO product obtainable by the method.
