ASCE : Calls for New Orleans Advisory Panel

Reston, VA -- The American Society of Civil Engineers (ASCE) today called for the creation of an independent, federally funded reconstruction advisory panel for New Orleans to serve as the primary advisor to local officials on the rebuilding of the city and immediate surrounding areas. The panel should be comprised of technical experts who would provide an objective review of all design and construction issues relating to the reconstruction and would be fully integrated with any federal agency involved in these efforts.

As proposed, the New Orleans Reconstruction Advisory Panel charter would be as follows:

The federally sponsored and funded advisory panel will serve as primary advisor to the Mayor of New Orleans and affected parish, city and state governments on the rebuilding of the city;

  • The panel will consist of experts from engineering, architecture, planning and other design and construction related fields;
  • The recommendations of the panel will include strategies to minimize the impact of future storm events and other hazards;
  • The primary goal will be to maintain and improve the way of life for the citizens of the metropolitan New Orleans area;
  • The focus of the panel will be on incorporating mitigative and sustainable measures into the reconstruction efforts;
  • The panel will serve as link to federal agencies working in support of the reconstruction effort; and
  • The panel will function in an advisory capacity only and will have no authority to mandate solutions.

The panel concept was developed with leading non-governmental organizations at a meeting held on September 6 in Washington, D.C. Sponsored by ASCE and The Infrastructure Security Partnership, the roundtable meeting was held to coordinate a unified response by the engineering, design and construction community to the devastation caused by Hurricane Katrina.

The Infrastructure Security Partnership (TISP) was established following the tragic events of September 11, 2001 as a forum for U.S.-based public and private sector non-profit organizations to collaborate on issues regarding the security of the nation's built environment, including resilience to natural and man-made disasters through effective and efficient planning, design, construction and operation. Membership includes more than 200 organizations and agencies representing more than 2 million individuals and firms.

Founded in 1852, ASCE represents more than 137,000 civil engineers worldwide and is America's oldest national engineering society. The society celebrated its 150th anniversary in 2002.

Hurricane Relief : ITT Offers Funds and Equipment

White Plains, NY -- ITT Industries has pledged $250,000 to the Red Cross to fund immediate hurricane relief, and has made available fluid technology equipment for delivery to Louisiana, Mississippi and Alabama, including dewatering pumps and reverse osmosis systems which could be vital to relief efforts. Additionally, the company has sent night vision equipment and personnel to assist in round-the-clock search and rescue efforts in the affected areas.

“ITT Industries is ready to offer our technical experience and equipment to provide emergency relief to the areas most impacted by Hurricane Katrina,” said Steve Loranger, Chairman, President and CEO of ITT Industries. “Removing the flood waters from New Orleans is a vital preliminary step to planning for recovery in that region. We’re prepared right now, to provide our equipment and expertise as well as water treatment equipment, wherever and whenever it is needed.”

ITT has installed more than 70 large turbine pumps in New Orleans over the years as part of the city’s flood control system. Together, these pumps are capable of pumping up to 2 billion gallons an hour. To supplement these in the hurricane’s aftermath, ITT has prepared a fleet of more than 100 large submersible pumps, routinely rented for dewatering projects, on standby to help remove the flood waters from New Orleans. Developed just prior to the “Great Midwest Flood of 1993,” these engine-driven pumps can each remove 20,000 gallons of water per minute. The company has also readied numerous smaller units capable of pumping between 100 and 15,000 gallons of water per minute.

Additionally, ITT has prepared chlorination and UV disinfection equipment to help provide potable water to victims of Hurricane Katrina. This equipment can provide up to 250,000 gallons of water per day. The company provided similar systems to Iraq and following the tsunami in Sri Lanka to provide clean drinking water for thousands of people.

ITT night vision equipment and training personnel are already in Louisiana, enabling searches to continue around the clock. The company donated 22 night vision goggles to police agencies, and has offered training in mission applications. Further, ITT imagers are providing real time satellite imagery to rescue and relief operations.

USFilter : Multiwash System Ordered for Albuquerque

WARRENDALE, PA -- The city of Albuquerque, N.M., has awarded USFilter, a part of Siemens Water Technologies, the contract to supply a filter system for the city’s new 92 million gallon per day (mgd) drinking water treatment facility. USFilter was selected to supply the filter underdrain, washtroughs, and granular activated carbon (GAC) media valued at approximately $2.5 million. The project was driven by the need to improve surface water quality by addressing taste and odor issues.

The filtration system consists of 12 filter cells for a total of 12,480 sq.ft. USFilter's direct retention Multicrete II™ underdrain system will support a 72-inch depth of AquaCarb® granular activated carbon and 12 inches of filter sand. Corrosion resistant plastic components are used in the entire underdrain system.

Collection of backwash waste will be provided with 72 ESSD™ type 316 stainless steel washtroughs equipped with patented Low Profile Multiwash® separator baffles. Selection of the Multiwash separator system was based on proven experience to retain GAC media at other large full-scale installations.

"We reviewed several filtration options for this project," comments CH2M Hill engineer Brock McEwen. "The proven track record of the Multiwash system with GAC media lead us to select it as the basis of design."

The combination of Multicrete II underdrains and Multiwash baffled washtroughs are in operation at hundreds of installations including lime softening, iron and manganese removal, surface water treatment and wastewater filtration. The open plenum underdrain system uniformly distributes air and water during backwash for powerful cleaning efficiency.

Multiwash baffles allow combined air-water backwashing while overflowing the washtroughs and minimize the separation between media and washtroughs. Backwash waste volume and cycle time are reduced while guaranteed media cleanliness and media loss prevention is provided. Systems in operation include single and multi-media beds including several large installations with GAC media.

The AquaCarb® granular activated carbon is ANSI/NSF Standard 61-classified for use in potable water applications. The carbon is manufactured by USFilter Westates Carbon from selected grades of bituminous coal. The carbon adsorbs dissolved organics, taste and odor compounds.

The plant was designed by CH2M Hill of Albuquerque, N.M., and will be installed by PCL/Triad Joint Venture of Albuquerque. The plant is scheduled to be operational by June of 2007.

GE : Plays Critical Role in 78 MGD Ultrafiltration Plant

TREVOSE, PA -- GE Infrastructure, Water & Process Technologies, a unit of General Electric Company, joined the City of Minneapolis today for the opening tour of the city's new Columbia Heights water filtration plant - the world's largest potable ultrafiltration (UF) plant. The plant utilizes GE's UF solutions to provide up to 78 million gallons per day (MGD) of potable water to over half a million Minneapolis residents.

Cryptosporidium is a waterborne protozoa that is harmful for humans to ingest and can cause symptoms that include fever, weight loss, dehydration, vomiting, and death. In 1993, Milwaukee battled a Cryptosporidium outbreak that claimed the lives of an estimated 100 residents. The Milwaukee outbreak prompted the Minneapolis Water Works to conduct a feasibility study that examined the city's risk factors, as well as remedies, possible solutions and technologies that would help safeguard the city's water. Upon completion of the study, Minneapolis, with its Peer Review Panel and Citizens Advisory Committee, determined that GE's UF technology was best-suited to aid the city in protecting its citizens.

GE's UF technology is a pressure-driven technology that provides a physical barrier to pathogens and is commonly used to remove suspended solids, bacteria, microorganisms, and viruses in potable water production. The Minneapolis plant combines GE's UF technology with NORIT membrane technology - creating a complementary system that results in the extremely effective removal of hazardous waterborne microorganisms and contaminants. The nationally recognized California Department of Health Services gave ultrafiltration the highest removal rate credits available.

GE's UF solutions are capable of delivering the following: consistent, superior water quality regardless of feed quality variations; dead-end operation resulting in low energy consumption; greater than 6 log (99.9999%) removal of Cryptosporidium and Giardia lamblia; highest certified removal of viruses - 4 log (99.99%); low chemical consumption; permeate SDI(15) less than 3; small system footprint and compact arrangement; and proven membrane life.

In addition to the opening of the City of Minneapolis' Columbia Heights plant, GE was recently awarded a contract by the City of Mankato, MN to provide ultrafiltration technology in upgrades to their water treatment plant. The Mankato plant, which will provide 12 MGD of potable water to city residents, will be the state's second largest UF plant and is expected to be on-line in September 2006.

The City of Minneapolis and City of Mankato plants will join GE's expanding ecomagination and water scarcity solutions portfolio, which includes a wide-range of customized water solutions designed to create new sources of usable water for the potable, industrial and agricultural sectors -- while lessening impacts on fresh water sources.

Mr. Hallberg needs help with activated sludge:

I am currently considering pure oxygen upgrade for our activated sludge plant, my questions are as follows;

  • What determines the maximum oxygen uptake of the microorganisms?
    I must assume that it depends partly on how much CO2 that is generated from the biomass.
  • There must be a situation where a balance between partial pressure of oxygen and partial pressure of CO2 in the system exists. At what pressures would those be?
  • What is the discharge rate of CO2 from the surface compared to oxygen?
  • Should the system be shallow and wide or deep and narrow?

What I am questioning is, there may be a limit to how much biomass can exist in the system based on how much oxygen can be consumed, depending on many factors one being CO2 discharge.  Can anyone advise on real plant situation behaviour?
