| abstract |
The present disclosure provides a depth filter medium comprising at least one elastomeric nonwoven web strengthened by combination with one or more structural support layers. The resulting material is particularly useful in the field of filtration, wherein particulates captured within the elastomeric nonwoven web can be readily released, such as by applying pressure to the web through backwashing. The elastomeric nonwoven web advantageously can stretch under such pressure and return substantially to its original structure and shape upon the removal of the pressure, rendering the filter available for reuse. |
