A method of cleaning a membrane in a membrane separation activated-sludge process. By the method, deposits adherent to the surface of a membrane used in a membrane separation activated-sludge process can be effectively scratched off and the membrane filtration rate can be prevented from decreasing. Membrane-cleaning particles in which the surface to be in contact with the water to be treated has been hydrophilized and has a surface roughness of 100-2,500 μm are introduced into a bioreactor. The particles are caused to flow by the lifting effect of air bubbles ejected from an aerator or by the fluidizing effect of a fluidizing means to thereby cause the particles to scratch off deposits adherent to the surface of a separation membrane element. Membrane-cleaning particles which are non-porous or have closed cells can be used. Membrane-cleaning particles having an antibacterial ingredient can be supported on the surface or in inner parts thereof.
