Additionally, GP reviewed the air quality inside the plant control rooms to determine if the hydrogen sulfide could cause mission critical hardware failure, as well as unpleasant odors and conditions for staff. The analysis found that both staff and equipment would benefit from a reduction in H2S levels, so the hunt began for a ...
The aim of the project is to develop and commercialise the IRON high performance handheld device for gas measurements. Achieving laboratory grade performance for sub-parts per billion (ppb) gas detection is possible through the use of proprietary mid-infrared laser spectroscopy combined with novel patented photoacoustic technology. The transitioning of its technology from fixed mount analysers to ...
The Problem: The Mighty Squirrel Brewery in Waltham, Massachusetts is in a strip mall. The landlord has asked them to control the odors that come from brewing beer, specifically, the odors coming from the kettle vents when the wort is boiling and the whirlpool vent when it is in operation. The landlords’ biggest complaint is the smell of rotting vegetables. The odors are noticeable up to ...
Envron co-operated with the Canadian Mushroom Growers Association, the Canadian Federal Government, Provincial Government and Greenwood Mushroom Farm on a full-scale mushroom bunker composting odor control project at Greenwood Mushroom farm. This work was based on earlier work conducted with the British Columbia Ministry of Agriculture that showed positive odor control with Ozone and mushroom ...
Generally, people do not perceive other common air pollutants, even if the exposure limit concentrations are exceeded. Lack of odour analysis adds on to that. On the contrary, odours can be perceived even at below-normal exposure limit concentrations. ...
Odors are very distinct air contaminants as they generate nuisances. The factors playing a role in the determination of odor annoyance are: odor concentration and intensity, frequency, appreciation, duration, synergy and location. ...
These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor these compounds online CHROMATOTEC® offers high meteorological solutions. ...
The ODP assessors detected a total of 32 different odorous VOCs; however, the intensities assigned by each assessor to particular VOCs varied. Moreover, some odorous VOCs were not detected by all assessors. For example, geosmin was detected by only two assessors. The use of a TD-GC-MS/ODP system for the analysis of odorous VOCs ...
French-family firm Chromatotec has retained its edge in the global market of gas analytics thanks to its uncompromising attitude to its expertise in specialised hazardous-area gas analysis systems. "Customers are always requesting high reactivity and good products. Through our complete approach, we offer support in different languages and provide answers to clients within 48 hours," commented Mr ...
In addition to providing a detailed analysis of all odor-causing compounds, Dr. Haupert discussed today’s most cutting-edge, eco-friendly odor control solutions. Here are some more insights from the article, which point to OMI Industries’ Ecosorb technology: Finally, natural odor control solutions can fully ...
The black-odor mechanism of Yitong River was analyzed based on survey and monitoring results. We found that organic matter is the main pollution source of Yitong River and its tributaries. A black-odor evaluation model that can describe the pollution of the Yitong River water system was developed, and this model has the parameters I = 0.21 [CODCr] + 0.18 [DO] – 0.36[NH3-N] + 0.91. The model ...
The Bordeaux-based company is using its odor and pollutant gases analysis solutions to propose references measures in the field of quality monitoring and their impact on environment. ...
This solution dedicated for monitoring and online analysis of odorous compounds in natural gas today received the ATEX certification for zone 1. ...
Odorous drinking water problem occurred repeatedly in one city in northern China in recent years. The uniqueness of this odor episode lay in two aspects: (1) the odorous chemicals were quite different from common odorants, such as geosmin and 2-MIB; and (2) it occurred repeatedly in different seasons during a time span of more than 2 years. The screening of odorants was the first and one of ...
TRS MEDOR system At the point of arrival of the wastewater at the stripping area of the plant, the polluted air is captured and thereafter passed in a circuit that neutralises it. These odors are caused by bacteriological fermentation. Successive chemical cleanings in the deodorisation towers neutralize these odors. The bad odors are largely ...

We evaluated the use of an electronic nose (E-Nose) consisting of ten non-specific metal oxide sensors for monitoring odors of wastewater from influent and effluent samples at three different wastewater secondary treatment plants in Alexandria, Egypt, over a 7-month period in association with causes of odor by standard laboratories of chemical ...
Towards providing greater insight into this issue, several activated carbon filters and biofilters treating odorous emissions from sewer systems in Sydney (Australia) were monitored by collecting and analysing gas samples before and after treatment. ...
