Although odor is not generally directly associated with toxic exposure problems, it may raise doubts and questions.
Odotech offers services to study the technological risks associated with atmospheric emissions. The analysis of technological risks determines potential hazards and establishes possible management/mitigation scenarios.
Technological and toxicological risk studies
To address this problem, Odotech conducts preliminary toxicological risk studies. The first stage consists of an inventory and the characterization of atmospheric sources of compounds that present a risk to human health. The results allow us to assess exposure and the resultant dose on the target population, to evaluate the potential long-term effects on health and to then quantify the risks to human health associated with the exposure.
Air Quality Studies
Odotech develops and performs ambient air quality studies, according to a scientific assessment process, in order to assess the impact of a project in terms of atmospheric emissions. The results define components that may be useful during project development, so that the regulatory requirements around a project may be satisfied.
Composting sites could generate odour nuisances in the environment if not operated optimally in terms of odour. The implementation of a continuous odour monitoring system, OdoWatch, based on e-nose technology allows operators to better understand how and when odour incidents occur and what actions can be taken to reduce emissions.
A continuous odour monitoring system, fitted with 5 e-noses, a weather station and an odour dispersion modelling software, was set up at one of the largest composting sites in Europe. Although several sources were identified from the beginning as being likely to generate odour nuisances, monitoring enabled the identification of the 0-3 week fermentation source as being responsible for 87% of the nuisances generated.
The operator’s efforts reduced odour nuisances which had increased by more than 40% over a 6-month period and by nearly 75% after 2 years. The nuisance level in inhabited areas was, to start with, relatively low, but was greatly reduced by the operator's diligence, using measurements made by the OdoWatch system in real time, and by continuous improvement of the techniques used.
If you are in the Sacramento, California area May 22-25, be sure to visit the WEF Residuals & Biosolids Conference & Expo at the Sacramento Convention Center. This year’s conference will focus on local and national perspectives on sustainable biosolids management technologies and programs that instill these new policies.
One of the sustainable technologies that will be presented is OdoWatch - the world's first real-time, continuous odor monitoring tool that helps leading-edge waste operators prevent and manage odors from their facilities.
Learn more about OdoWatch at the Kruger booth #212. See how it can save you time & money preventing and resolving odor complaints quickly and accurately. OdoWatch can demonstrate odor performance to show compliance with local air regulations.
Kruger also has state-of-the-art technologies that optimize energy consumption and streamline the solids handling process at wastewater treatment plants. See and hear what's new at Kruger!
