WEF Conference on Odors and Air Pollutants 15-18 April 2012 in Kentucky, USA.

Wef odors 2012Next conference on Odors and Air Pollutants 2012 organized by the Water Environment Federation (WEF) will take place in the Kentucky International Convention Center, in Louisville, Kentucky.

The conference will take place in April 15th to 18th, 2012 and there will be also an exhibition the 16th and 17th, 2012. Registration will open in January, 2012. This year’s Odors and Air Pollutants Conference will bring together environmental professionals from the technical and regulated communities to discuss state-of-the-art techniques for the assessment and control of odors and air pollutants while promoting the use and acceptance of effective innovative technologies.

 The 2012 Conference will kick off with two keynote speakers presenting two interesting messages. The first half will introduce Lauren Anderson, Executive Director of the Louisville Metro Government Air Pollution Control District, who will highlight the last ten years of the highly acclaimed Strategic Toxic Air Reduction (STAR) program and its success in reducing high levels of toxic chemicals in the air in specific Louisville neighborhoods. The second keynote speaker is Alex Novak, Director of Operations at the Louisville Metropolitan Sewer District, who will offer a presentation on balancing odor control needs with other important treatment plant functions and will discuss options on full service odor control contracts.

This year's Odors and Air Pollutants 2012 Conference technical program will stress real-life experience and lessons learned. The conference will cater to the following technical session topics: 

Methods of Sampling, Measuring, and Estimating Emissions Odor and emission Control Systems
Odor Control Planning and Monitoring Biological Odor Control
Fate and Odor Modeling Innovative Technologies
Collection System Odors and Corrosion Design of Odor Control Systems
Emission from Biosolids Collection Systems Tunnel Ventilation
