Filter With Captured Membrane

摘要

The present inventive concept relates to devices and methods for pressure filtration utilizing spiral wound membranes, in which the volume between the filter membrane and the filter housing is partially or essentially completely filled with an impermeable material. The resulting device permits rapid filtration rates with improved pressure resistance and reduced contamination and microbial growth within the filtration device.
