ABSTRACT:
Method of and apparatus for separation of solids from a liquid employs an elastic sheet filter which has pores of diameter larger than an average diameter of the solid and smaller than the maximum diameter thereof. The liquid is filtered under pressure by a filtered residue layer developed on the sheet filter. Then liquid is rapidly introduced to the sheet filter portion from the reverse direction to liquid flow occured during the filtration of the liquid so that the sheet filter and filtered residue layer pressed during the filtration is rapidly pressed in the reverse direction, whereby the filtered residue layer is flaked out in the liquid and separated therefrom.
