Beschreibung
Zusammenfassung:	A method for producing a sugar solution, the method including a step for filtering a saccharified solution from a cellulose-containing biomass derivative by passage through a nanofiltration membrane and/or a reverse osmosis membrane, wherein the method for producing a sugar solution includes a two-stage washing step for washing the nanofiltration membrane and/or reverse osmosis membrane using an acid wash solution after filtration, then washing using an alkali wash solution. Provided is a method for effectively washing a contaminated separation membrane in a method for producing a sugar solution by treating a sugar solution derived from cellulose using a nanofiltration membrane and/or a reverse osmosis membrane.
