Abstract
Compacted filter beds comprising a non-sintered, buoyant filter medium may be useful in fluid filtration apparatuses and methods. For example, a method may include filtering a first fluid through a filter bed that is compacted, the filter bed comprising a non-sintered, buoyant filter medium that is mechanically compacted; and backflushing a second fluid through the filter bed so as to fluidize the non-sintered, buoyant filter medium.
