PROBLEM TO BE SOLVED: To provide an operation support device which can reduce treatment cost for operation control of a membrane filtration apparatus. SOLUTION: The operation support device for a membrane filtration apparatus is equipped with a calculation means which, when the washing process for consuming a large amount of electric power is operated in a nighttime low in an electric power charge and the filtering process consuming a small amount of electric power is operated in a daytime high in an electric power charge, calculates recommended operation amounts of the membrane filtration apparatus containing at least a filtration time, and recommended operation amounts of a washing apparatus containing at least a washing time from present operation information of the membrane filtration apparatus containing a transmembrane pressure difference and a filtration flow rate of the membrane filtration apparatus filtering raw water, water level information of a distributing reservoir, an increasing ratio of the transmembrane pressure difference at a filtration time from the past or a decreasing ratio of the filtration flow rate from the past obtained from a planned water amount information given beforehand, and the planned water amount information input through interfaces.
