Filtration membranes comprising a microporous sheet of polyolefin grafted with a poloxamer are described. In an embodiment, the poloxamer is that supplied under the trade name PLURONIC™ P-123 and the polyolefin is poly(ethylene). The membranes provide the advantage of being tolerant to the cleaning agents used in clean-in-place protocols and can be used to remove particulates from these aqueous feed streams.
Composite membranes having a film of poly(ethenol) (polyvinyl alcohol; PVA) adhered to a microporous sheet of polyolefin are disclosed. The microporous sheet is made hydrophilic by grafting of the polyolefin, e.g. poly(ethylene), with a preformed polymer before adherence of the film of PVA. The composite membranes are chlorine tolerant with high levels of protein rejection making them particularly suitable for use in the extraction or recovery of water from feed streams in the beverage and food industries, including dairy.
Asymmetric composite membranes and methods for their preparation are disclosed. The membranes comprise a cross-linked poly(vinyl alcohol) polymer coated on a film of cross-linked sulfonated poly(ether ether ketone) adhered to a sheet of hydrophilicitized microporous polyolefin. The microporous polyolefin is typically microporous poly(ethylene). The membranes have improved selectivity with the regard to the rejection of solutes in reverse osmosis and ultrafiltration applications.
