PROBLEM TO BE SOLVED: To provide a reverse osmosis membrane apparatus capable of being reduced in its load fluctuations when operated by power due to a natural energy source, and an operation method therefor. SOLUTION: The reverse osmosis membrane 20 is equipped with generating means 10 and 12 for generating electricitiy by a natural energy source, a pressure means (high pressure pump) 6 for pressurizing the supply water to the reverse osmosis membrane (RO) module 8 by power generated by the generating means 10, the pressure accumulation means (accumulator) 8 and a supply water distribution means connected to the pressure means and a pressure accumulation means and distributing the supply water corresponding to an excess pressure energy to the pressure accumulation means and discharging the supply water corresponding to an insufficient pressure energy from the pressure accumulation means when the pressure energy of the pressure means is less than a predetermined value.
