Abstract
Durable asymmetric composite membranes consisting of a film of cross-linked poly(ether ether ketone) adhered to a sheet of hydrophilic microporous poly(ethylene) are disclosed. The membranes are suitable for use in the recovery or removal of water from feed streams where repeated clean-in-place protocols are required such as in the processing of dairy products.
