    • According to one embodiment of the present invention, a method for backwashing of a reverse osmosis membrane includes a washing process of washing a second reverse osmosis membrane included in a second module by bypassing some or total of a second influent while supplying a first influent treated by a first module including a first reverse osmosis membrane to the influent of the second module. The method for backwashing of a reverse osmosis membrane enables washing of a reverse osmosis membrane without stopping the whole process of water treatment, maintains processing quantities of a module not performing washing process to maintain the processing quantities of the total system as well as performs the washing process of the reverse osmosis membrane without separately and excessively inserting highly concentrated salt water; thus, additional contamination in concentrated water due to slat water does not occur and washing reverse osmosis membrane can be processed without a structural change in the water treatment system.
