Abstract
The disclosed system and apparatus can be used to improve the operation of a membrane bioreactor wastewater treatment system. The system may include one or more membrane filtration modules having a proximal end and a distal end in which each module houses one or more membrane filters. The system and method can be configured to include the steps of interrupting the introduction or flow of feed liquid, allowing at least a portion of the feed liquid present in the one or more membrane filtration modules to drain therefrom, and to resume the introduction or feed of the feed liquid. Optionally, the system and method can include the step of allowing at least a portion of the recovered permeate to backflush the one or more membrane filters.
