A method of cleaning a filtration membrane includes an alkaline treatment process for supplying an alkaline agent 24 to seawater 11 for a predetermined period of time and filtering the seawater 11, to which the alkaline agent 24 is supplied, through a reverse osmosis membrane 15 during a filtration treatment operation, and a neutralization treatment process for supplying an acid agent 26 to the seawater 11 for a predetermined period of time and filtering the seawater 11, to which the acid agent 26 is supplied, through the reverse osmosis membrane 15 after the alkaline treatment process. |
