System and method for withdrawing permeate through a filter and for cleaning the filter in situ
First Claim
1. A system for withdrawing permeate from a substrate, said system comprising:
- a vessel configured to contain substrate;
two or more compartments configured to receive substrate from said vessel and to return a portion of received substrate to said vessel;
a filter positioned at least partially within each of said compartments and configured to separate permeate from substrate during operation of said filter;
at least one of said compartments being configured to contain cleaning solution and substantially prevent cleaning solution from contacting substrate in said vessel during cleaning of said filter; and
said system being configured for cleaning said filter in situ in at least one of said compartments while operating said filter in at least one other of said compartments.

Abstract
A system is provided for withdrawing permeate from a substrate. The exemplary system includes a vessel configured to contain substrate, two or more compartments configured to receive substrate from the vessel and to return a portion of received substrate to the vessel, and a filter positioned at least partially within each of the compartments and configured to separate permeate from substrate during operation of the filter. At least one of the compartments is configured to contain cleaning solution and substantially prevent cleaning solution from contacting substrate in the vessel during cleaning of the filter. The exemplary system is configured for cleaning the filter in situ in at least one of the compartments while operating the filter in at least one other of the compartments. A method for adapting a filtration system for cleaning thereof and a method for withdrawing permeate from a substrate using a filtration system are also provided.

17. A system for withdrawing permeate from a substrate, said system comprising:
-
a vessel configured to contain substrate;
two or more compartments positioned at least partially within said vessel, said compartments being configured to receive substrate from said vessel and to return a portion of received substrate to said vessel;
a filter positioned at least partially within each of said compartments and configured to separate permeate from substrate during operation of said filter;

18. A method for withdrawing permeate from a substrate using a filtration system, said method comprising the steps of:
-
(a) introducing substrate from a vessel into two or more compartments for contact with a filter positioned at least partially within each of the compartments;
(b) returning a portion of received substrate from the compartments to the vessel;
(c) cleaning a filter associated with at least one of the compartments in situ; and
(d) operating a filter associated with at least one other of the compartments, thereby withdrawing permeate from substrate received in the compartment through the operating filter. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 31, 32)

33. A method for adapting a filtration system for cleaning thereof, said filtration system being configured to remove permeate from substrate contained in a vessel, said method comprising the steps of:
-
(a) positioning at least one compartment to receive substrate from the vessel and to return a portion of received substrate to the vessel;
(b) positioning a filter at least partially within the compartment for separating permeate from substrate during operation of the filter; and
(c) configuring the compartment to contain cleaning solution and substantially prevent cleaning solution from contacting substrate in the vessel during cleaning of the filter. - View Dependent Claims (34)
