White paper: WWTP odor control chemical optimization using e-Noses
|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.
