ABSTRACT:
A filter bed for removing impurities from a liquid stream is described. The filter bed comprises a mat of pliant fibers and relatively stiff fibers. The filter bed may additionally include adsorbent particles. The filter bed can provide desirable filtration efficiencies while exhibiting relatively low operating differentials. A method for separating impurities from a liquid which employs the filter bed is also described.
