The unfiltered liquid is provided to the filter under positive pressure, when liquid moves in downward direction and causes its way through opening up on sides of the filter plates. And because the liquid stress increases, the filter media retains the foreign atoms and helps just apparent filtrate to move by the central medium formed by interlocking pressure cups to the opening. Filtration by filter pads is continuous up to the cake holding capability of the unit is attained or till the filtrate becomes extremely slow owing to cake resisting.
