Package Assembly For Piperazine-Based Membranes

View page
US Patent:
20030098272, May 29, 2003
Filed:
Oct 5, 2001
Appl. No.:
09/972650
Inventors:
Allyn Marsh - Eden Prairie MN, US
Russ Schaffenberg - Bloomington MN, US
Steven Jons - Eden Prairie MN, US
Roy Davis - Midland MI, US
International Classification:
B01D063/10
US Classification:
210/321740, 210/321830
Abstract:
A package assembly comprising a sealed water-impermeable bag enclosing: a spiral wound filtration element comprising a piperazine-based membrane, and an aqueous solution comprises a substantially non-oxidizable buffer having capacity to sequester at least 0.0025 moles per liter of hydrogen ions. The assembly preferably further includes a reducing agent. The assembly provides improved preservation for piperazine-based membranes and elements incorporating such membranes.

Apparatus For Treating Solutions Of High Osmotic Strength

View page
US Patent:
20070272628, Nov 29, 2007
Filed:
Feb 25, 2005
Appl. No.:
10/590423
Inventors:
William Mickols - Chanhassen MN, US
Allyn Marsh - Lakeville MN, US
Martin Peery - Bloomington MN, US
Steven Jons - Eden Prairie MN, US
Markus Busch - Drusenheim, FR
International Classification:
B01D 63/12
US Classification:
210790000, 210255000, 210321650, 210336000, 210806000
Abstract:
The present invention pertains to an apparatus and method for treating a solution of high osmotic strength, especially seawater and solutions of greater than 20 bar osmotic pressure, by passing the solution through a vessel containing spiral wound reverse osmosis or nanofiltration elements. The vessel contains at least three elements in series and at least two of these elements have standard specific fluxed that differ by at least 50%. The invention allows a more even flux distribution within a filtration system to be obtained, and it may advantageously be combined with variations en element construction and feed spacers.

Composite Polyamide Membrane Including Dissolvable Polymer Coating

View page
US Patent:
20150367288, Dec 24, 2015
Filed:
Feb 28, 2014
Appl. No.:
14/758575
Inventors:
- Midland MI, US
Allyn R. Marsh III - Lakeville MN, US
Assignee:
Dow Global Technologies LLC - Midland MI
International Classification:
B01D 67/00
B01D 71/12
B01D 71/56
Abstract:
A thin film composite membrane including a thin film polyamide layer positioned between a porous support and an outer coating, and a humectant; wherein the membrane has an A-value of at least 8 l/mhr/bar when tested at 25 l/mhr with pure water at 25 C. for one hour, and wherein the outer coating comprises a dissolvable cellulose polymer provided at coverage of at least 10 mg/mthat substantially dissolves from the membrane after one hour of continuous cross-flow of water at 25 l/mhr and 25 C.
