US Patent:

6210582, Apr 3, 2001

Filed:

Jun 10, 1999

Appl. No.:

9/329538

Inventors:

Michael Arthur Del Vecchio - Flemington NJ
Robert Eben Loudon - Howell NJ
Paul Matthew Sutton - Danbury CT

Assignee:

Envirogen, Inc. - Lawrenceville NJ

International Classification:

B01D 6502

US Classification:

210636

Abstract:

A system is provided for withdrawing permeate from a substrate through a filter and for cleaning the filter in situ. The system includes a vessel configured to contain a substrate and a compartment connected to receive substrate from the vessel and connected to return a portion of received substrate to the vessel during normal operation of the system. The system also includes a filter positioned at least partially within the compartment to withdraw permeate from substrate in the compartment during normal operation of the system. A source of cleaning solution is connected to the compartment to deliver cleaning solution into the compartment and into contact with the filter during cleaning operation of the system. The compartment facilitates circulation of substrate in the vessel during normal operation of the system and substantially prevents introduction of cleaning solution from the compartment into contact with substrate contained in the vessel during cleaning operation. A method is also provided.

Assignee:

Envirogen, Inc. - Lawrenceville NJ

International Classification:

B01D 6502

US Classification:

210636, 2101952, 210332, 21032169, 210617, 210797

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.

Assignee:

Envirogen, Inc. - Lawrenceville NJ

International Classification:

B01D065/02

US Classification:

210636, 2101952, 2102572, 21032169, 210805

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.
