Energy-Efficient Biological Treatment System With Filtration Membrane
US Patent:
7179370, Feb 20, 2007
Filed:
May 23, 2006
Appl. No.:
11/439318
Inventors:
Michael A. Dimitriou - Richmond VA, US
Joseph G. Krall - Grafton WI, US
David Rice - Port Washington WI, US
Velupillai Yogendran - Warwickshire, GB
Roger J. Byrne - Mequon WI, US

Assignee:
ITT Manufacturing Enterprises, Inc. - Wilmington DE
International Classification:
C02F 3/00
US Classification:
210151, 210150, 210220, 210615
Abstract:
A membrane filtration system comprising one or more submerged ultrafiltration or microfiltration membrane assemblies at ambient pressure, each membrane assembly positioned 100–240 mm from a nearest wall, baffle, or adjacent membrane assembly and no more than 1 meter above a floor and at least 150 mm below the liquid level. Mixed liquor is discharged underneath each membrane assembly to create a vertical flow velocity in a range of 1–8 mm/second along an entire length of the membrane assembly. In a sequenced batch reactor system, a coarse bubble air diffuser for scouring each membrane assembly is supplied with air only during the backwash cycle of the filtration system and not during the filtration cycle. In a membrane bioreactor system, the biological treatment section is physically separated from the filtration section and fine bubble air diffusion is used in the biological treatment section.
Strip Diffuser
US Patent:
7255333, Aug 14, 2007
Filed:
Aug 13, 2003
Appl. No.:
10/639774
Inventors:
Thomas J. Casper - Waukesha WI, US
Mark A. Schoenenberger - Cedarburg WI, US
Brad D. Laubenstein - Fort Washington WI, US

Assignee:
ITT Manufacturing Enterprises, Inc. - Wilmington DE
International Classification:
B01F 3/04
US Classification:
2611221, 261124, 261DIG 70
Abstract:
Membrane strip diffusers are disclosed, useful for example in aerating wastewater in activated sludge plants. These diffusers have membranes, diffuser bodies and gas conduits elongated in the same general direction. Such conduits may be attached to or formed integrally with the diffuser bodies. Gas chambers form beneath the membranes when they inflate, and these are separate from but communicate with the gas conduits, e. g. , through passageways distributed along the lengths of the membrane supports. Preferably, the passageway flow cross-sections are small, thus tending toward uniform distribution of gas along the membrane's length. Ways to edge- and end-seal the membranes to the diffuser bodies are also disclosed.

International Classification:
B01F 3/04
US Classification:
2611221, 261DIG 70
Abstract:
Membrane strip diffusers are disclosed, useful for example in aerating wastewater in activated sludge plants. These diffusers have membranes, diffuser bodies comprising gas conduits and, in addition to the conduits, integral membrane supports elongated in the same general direction. Such conduits are for example co-extruded with the diffuser bodies. The supports are apertured to discharge gas into chambers formed beneath the membranes when they inflate, and the membranes have pores to discharge the gas. Ways to edge- and end-seal the membranes to the diffuser bodies and ways to support the diffusers are also disclosed.
