ABSTRACT:
A system is provided for withdrawing permeate from a substrate. The exemplary system includes a vessel having a wall configured to contain substrate, a compartment positioned adjacent the wall of the vessel and configured to receive substrate from the vessel, and a filter positioned at least partially within the compartment and configured to separate permeate from substrate during operation of the filter. The compartment is configured to contain cleaning solution and substantially prevent cleaning solution from contacting substrate in the vessel during cleaning of the filter.
