About the 2011 NOM Conference

 

 

Standing by his poster, Philippe Schmitt-Kopplin of Helmholtz Zentrum München in Germany was both a keynote speaker and a poster presenter.

The Fourth International Water Association (IWA) Specialty Conference on Natural Organic Matter (NOM) was the fourth in a series of international conferences devoted to better understanding the dynamics and impacts of NOM in drinking water, wastewater, recycled waters, natural waters, and marine systems.

 

The term "NOM" describes organic matter (originating from plants and animals) that has undergone biological and chemical alterations, often giving water a "brownish" look. It can cause the formation of disinfection byproducts during the water treatment process, which may have adverse human health effects.  In wastewater, NOM is referred to as "effluent organic matter" (EfOM); it can create challenges with membrane treatment and reuse.  In natural systems, NOM is referred to as "dissolved organic matter" (DOM), and is known to control a variety of environmental and biogeochemical processes. 

 

At the conference, engineers and scientists from around the world highlighted the latest research on various aspects of NOM in water resources.  Research from over 25 countries was represented, including the U.S., Canada, Australia, Germany, England, China, Saudi Arabia, and many others. 

 

The conference spanned 3 days and featured approximately 200 oral and poster presentations. Four presentations were given by keynote speakers, and a special dinner presentation included the viewing of the 25-minute documentary preview, "Running Dry: Beyond the Brink," which was introduced by producer Jim Thebaut. 

 

Conference attendees had the option to tour the Groundwater Replenishment System in Orange County, California, which was described by attendees as a "practical experience" that "provided a good background for the applied talks on water treatment."

In addition, the conference featured a tour of the Groundwater Replenishment System (GWRS), located in Fountain Valley, California. GWRS is the largest advanced water purification facility in the world for indirect potable reuse; it uses microfiltration and reverse osmosis to eliminate NOM from wastewater as part of the disinfection process.

 

Altogether, more than 230 people attended the conference, representing personnel from academia, government agencies, water utilities, research organizations, and manufacturing and consulting firms. 

 

Attendees described the conference as well organized, with a diversity of speakers (including "giants in the field") and topics that provided valuable information (such as learning how utilities are solving problems).  Having time to network and sharing ideas with other scientists were considered highlights of the conference.

 

The next IWA conference on NOM is expected to held in Perth, Australia, in 2013.

2011 NOM Conference Proceedings

 

 

The 2011 NOM Conference featured over 200 oral and poster presentations.  Presenters also had the option of submitting a 10-20 page paper. The conference proceedings are made up of the presentations and papers prepared for this conference. 

Susan Richardson, a special luncheon speaker, addressed the formation and toxicity of disinfection byproducts.

 

The conference proceedings are available to download as individual PDF files.  Please note that some files are larger than others and may take longer to download.
