Abstract
A diffusion pipe is provided in which the air diffusion efficiency can be quickly recovered just after conducting a cleaning process for the diffusion pipe with a cleaning solution supplied into the membrane support body, and in which air diffusion is evenly and constantly provided. The diffusion pipe includes a membrane body made of a viscoelastic material and formed in a tubular shape having an inner surface and an outer surface, and a tubular membrane support body that supports the membrane body from inside of the membrane body. The membrane body has a plurality of diffusion slits cutting therethrough between the outer surface and the inner surface. The membrane support body has through-holes on an upper side and a lower side thereof. The diffusion slits are not provided in a region of the membrane body corresponding to the through-holes.
