摘要：
A method for cleaning a filtration apparatus comprising a plurality of membranes immersed in at least one tank containing the effluent to be treated. According to the method, the effluent is at least partially removed from the tank to expose the membranes to the air, and at least one cleaning solution is fed through said membranes in the opposite direction to the effluent filtration flow by delivering said cleaning solution to the permeate side of said membranes.
