Abstract:
A solid-liquid filtering system comprising:a network support having an upper lid, lower lid, means for drawing liquid though a said lid, and a porous frame extending between the upper and lower lids; a filter medium of a band of monofilaments, the monofilaments having a diameter of about 0.3 mm or less, disposed on an outer surface of the porous frame, one end portion of the band of monofilaments secured to the porous frame and another end thereof being floatable; the band of monofilaments formed as an inner layer of filaments and an outer layer of filaments, the filaments of the inner layer having a diameter less than a diameter of the filaments of the outer layer; such that when liquid is passed through the filter medium and then through the network support, solids are removed therefrom and collected on the filter medium, and when liquid is passed, as a backwash liquid, through the network support and then through the filter medium, the other end of the monofilaments float and collected solids thereon are released.
