Flat-sheet membrane filter assemblies require open space around equipment to form a viable path for an internal recycle or roll pattern. Creating a dedicated roll pattern for individual filter assemblies is space intensive and imposes process constraints on tank dimensions. A hollow wall or series of pipes forms a recycle wall designed to consolidate roll patterns and reduces space requirements. The recycle wall is designed such that the structural components also serve as a mixed liquor distribution system for the necessary roll pattern. Fixed vertically oriented conduit and sectional channel pieces allow for easy access and removal of membrane filter assemblies installed side by side. Feeding mixed liquor, air and or influent to the bottom of filter assemblies via submerged conduit improves process efficiency when coupled with return channels spaced not more than 10 feet away and above assemblies. The system is particularly advantageous for flat-sheet membrane filter units used in SMBR applications but is adaptable to other technologies including tubular and hollow-fiber membrane filter assemblies.
