The Florida Water Resources Conference is planned for April 29 through May 4 in Orlando, Florida at the Renaissance SeaWorld Resort. There will be a two-day technical program covering topics in wastewater, collection systems, regulatory issues and potable systems, to name but a few. Odor in wastewater treatment plants is one of the many topics that will be presented.
Visit Booth #804 - 807, where Kruger (a Veolia Water company) will be located at MTS Environmental booths. MTS, as a representative for Kruger, provides the OdoWatch technology to municipal wastewater treatment plants in Florida. Kruger will have on display a functional model of the OdoWatch eNose. Kruger Product Manager Sharon Paterson will be there to answer your questions about OdoWatch, and why several U.S. municipalities rely on it every day for proactive odor management.
Florida Water Resources Conference, Inc. ("FWRC") is a non-profit 501(c)3 organization, which provides an annual educational and technical, multi-day conference servicing individuals in the water and wastewater industry. FWRC is a joint conference of the Florida Section of the American Water Works Association, the Florida Water Environment Association, and the Florida Water and Pollution Control Operators Association.

The first permanent US installation of a unique technology that can actually “smell” an odor problem before it occurs has been on line in Tucson, Arizona, since 2009.
The Roger Road Wastewater Reclamation Facility (RRWRF) –TucsonAZ-is an older 41-MGD secondary wastewater treatment facility. Last upgraded and expanded in 1985, the Roger Road WRF was well known for having odor emission problems. Pima County Regional Wastewater reclamation Department completed in 2007 over 7-million dollars worth of odor control improvements at the facility. The facility is located along the banks of the Santa CruzRiverwash, at the base of theTucson Mountainsand adjacent to the I-10 Freeway.
This plant has odor emission sources:
As mentionned by Mr. Dennis Froehlich MS PE, System Wide Odor Control, Engineering Manager,Pima County, during his last presentation at the WEF 2012 Odors & Air Pollutants conference (The Relative Benefits of Dynamic vs Steady-State Continuous Odor Emissions Dispersion Monitoring for Multiple Sources) ''All of these sources have in common one characteristic: significant intermittent (read: dynamic) emissions driven by diurnal fluctuations in the plant processes and local meteorological conditions. So first they have to be identified and then quantified before they can be constructively addressed with a control plan. This meant continuous emissions monitoring.''
In January 2009, the OdoWatch Odor Continuous Monitoring System was installed for source emissions and controls monitoring to provide operators a consistent means of odor event awareness, process issue identification, and receptor impact estimation.
This system continuous emission monitoring system, the Odowatch System, employs a network of electronic noses monitoring odor and a local 10-meter tower with a meteorological station transmitting continuous emissions and met data via radio to a signal transceiver and router sending the data to a central modeling server. This server uses the data to update a locally calibrated Aermod dispersion model and serve the data in realtime to a windowing webpage presenting all of the data, plume map, alerts, and configuration data in four windows. This system also provides user configurable sampling locations where odor data at a given location are estimated from them model and saved.
OdoWatch®, operational at the Roger Road Wastewater Reclamation Facility, where six e-noses (electronic noses) calibrated to smell odors like the human nose are installed at the facility. The unit performs real-time air dispersion modelling to generate a colour-coded plume indicating the level of odour on a map of the site.
The odor monitoring system is capable monitoring facility’s compliance performance in terms of odor concentrations for nuisance threshold at fenceline, assumed as 7 D/T.
The odor is quantified by the system, and if the level begins to approach the threshold that can be perceived as a nuisance by a human nose, an alert notifies operators that actions must be taken to mitigate the situation. OdoWatch® can also be used to determine which source at a facility is causing the alert.
Mr. Froehlich reported that ''...this system is clearly state of the art... As a result of the monitoring, between 2009 and 2011, the low-pressure digester gas system was rebuilt, a flare shroud was designed and installed to shield the laminar flame from winds, and a chemical feed system was improved for chemical sulfide control in the primary clarifiers.''

Odors and Air Pollutants 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 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 |

| Odors are a natural byproduct of wastewater treatment, and a problem that has caused no shortage of headaches for cash-strapped public officials. But sanitation engineers in a Virginia Beach wastewater treatment plant have a powerful new tool to measure and minimize odors at their facility, thanks to an advanced new monitoring system based on electronic noses. |
 |
Designed to provide real-time, continuous measurements of odor emissions, the OdoWatch odor monitoring system gives sanitation workers the ability to see how much odor emissions their facility is producing, track what direction the wind is carrying them and how far the odors extend, all in a simple, automatically generated live webpage. The Virginia Beach WWTP used this tool to evaluate a new chemical treatment process, giving them a clearer picture of how much chemical to apply and when, thus tailoring their treatments in a way they never could before. After more than 18 months of research in real-life conditions, the system has delivered on its promise.
Since October 2009, three electronic noses have been monitoring odor emissions at the Chesapeake-Elizabeth Treatment Plant (CETP) in Virginia Beach. The Hampton Roads Sanitation District (HRSD), which covers 2,100 square miles of eastern Virginia, turned to OdoWatch in search of a more advanced, less costly technique to manage odors at the plant.
The results of this study will be presented at the next WEF Odors and Air Pollutants 2012. You can already access it by downloading the white paper on WWTP odor control chemical optimization using Electronic Noses.
