Abstract: [Problem] To provide a filter device capable of stably filtering, at a fixed flow rate, a liquid to be treated. [Solution] This filter device comprises: one or a connected plurality of first units, each comprising a first separation membrane part that separates a liquid to be treated in a first storage tank into a first filtered liquid and a first non-filtered liquid, a first takeout tube that takes out the first non-filtered liquid, a first adjustment unit that keeps the flow rate of the first filtered liquid substantially constant, and a first liquid level meter that detects the liquid level in the first storage tank; a second unit comprising a second separation membrane that separates a storage liquid in a second storage tank in which the first filtered liquid is accumulated into a second filtered liquid and a second non-filtered liquid, a second takeout tube that takes out the second non-filtered liquid, a second adjustment unit that keeps the flow rate of the second filtered liquid substantially constant, and a second liquid level meter that detects the liquid level in the second storage tank; a first control unit that controls the liquid level in the first storage tank on the basis of a measurement value from two connected first units, or a measurement value from a connected first unit and second unit; and a second control unit that controls the liquid level in the second storage tank on the basis of a measurement value from the second unit.

Abstract: The present invention relates to a method for producing a high-quality sugar liquor from a cellulose-containing biomass with high efficiency. More specifically, the present invention relates to a method for producing a sugar liquor, said method comprising: a step of causing an alkaline aqueous medium to pass through a cellulose-containing biomass to produce an alkaline filtrate; a circulation filtration step of causing the alkaline filtrate to pass through the cellulose-containing biomass repeatedly to produce a cellulose-containing solid material; and a step of hydrolyzing the cellulose-containing solid material to produce the sugar liquor.

Abstract: In solid-liquid separation of a saccharified liquid by filtration through a microfiltration membrane, the filtration performance can be increased by adjusting the lignin content in a pretreated product derived from a cellulose-containing biomass to not more than 8.5% to promote formation, on the membrane surface, of a cake in which the solid component in the saccharified liquid is concentrated. Collection of the cake formed on the membrane surface allows efficient solid-liquid separation of the saccharified liquid with the microfiltration membrane.
