Abstract: The present invention provides a cleaning method of a membrane for cleaning a membrane by air diffusing through an air diffusion device installed on the lower part of the membrane. The air diffusion can be repeated in order of a first air diffusion process (A1), a stop process (S), and a second air diffusion process (A2), and can control a time ratio (A1:S) of the first air diffusion process (A1) and the stop process (S) or a flux ratio of the first air diffusion process (A1) and the second air diffusion process (A2) with a specific ratio. The time ratio and the flux ratio can be constantly or variably changed, and the stop process can be performed with respect to a period of an accumulated air amount or a time period.
