Abstract
An apparatus for effecting filtration, clarification and purification of liquid which comprises a housing containing a filter element made up of a plurality of layers of adsorbent material, comprising a porous, non-woven fibrous matrix in which is included an adsorbing agent for removing dissolved or suspended matter from the liquid, and a plurality of layers of liquid-permeable material. The layers of adsorbent material and liquid-permeable material are interdigitated in a stack between liquid impervious walls, and the flow of liquid through the filter element is along path generally parallel to the confronting surfaces of the layers of adsorbent material and liquid-permeable material. A process for removing dissolved, suspended or particulate matter from a liquid containing same, utilizing the filter apparatus, is also disclosed.
