ABSTRACT:
A layered filter composite comprises a filter medium, and on the upstream surface thereof a homogeneous or graded layer of nonporous spherical glass microbeads as a filter aid. A method for filtering or prefiltering a liquid mixture is disclosed wherein a layer of glass microbeads is used as a filter or filter aid. The layered filter composite is useful in analytical applications as well as in large scale industrial and remedial (clean-up) applications.
