Abstract: The present invention relates to a method for operating a separation membrane module including a separation membrane having a first face and a second face, a liquid-to-be-filtrated flow channel along which liquid to be filtrated which is to be fed to the first face flows, and a permeated-liquid flow channel along which permeated liquid obtained from the second face flows, the method including: a filtration step of obtaining permeated liquid containing components that become insoluble when coming into contact with acids by feeding liquid to be filtrated to the liquid-to-be-filtrated flow channel; a first water substitution step of substituting liquid in the permeated-liquid flow channel with water, after the filtration step; a first chemical cleaning step of performing backwashing by causing an acidic chemical solution to flow from the second face toward the first face of the separation membrane, after the first water substitution step; and a second water substitution step of substituting liquid in the permeated-liquid flow channel with water, after the first chemical cleaning step.
