Currently, an external membrane system adopted in landfill leachate treatment is generally a cross-flow tubular ultrafiltration membrane. Namely, the circulating pump provides a certain flow velocity (3-5 m/s) for the mixed liquid (sludge), so that the mixed liquid forms a turbulent flow state in the tubular membrane, and the sludge is prevented from depositing on the surface of the membrane.
