Comparison of two standard odor intensity evaluation methods for odor problems in air or water
Government agencies responsible for ensuring healthful water and/or air quality are often faced with resolving public complaints of nuisance odors. Understanding variations in odor intensity may ultimately lead to the establishment and application by such agencies of quantitative limits for effective odorant control. An odor panel was trained in suprathreshold odor intensity evaluation using ...

Case study of odor and indoor air quality assessment in the dewatering building at the Stickney Water Reclamation Plant
Indoor air quality (IAQ) and odors were determined using sampling/monitoring, measurement, and modeling methods in a large dewatering building at a very large water reclamation plant. The ultimate goal was to determine control strategies to reduce the sensory impacts on the workforce and achieve odor reduction within the building. Study approaches included: (1) investigation of air mixing by ...

Do People in Properties near Landfills need to be Concerned about Health & Safety Issues Related to Odors?
Many residential communities and businesses have been built over the years close to landfills as towns and cities have grown. For people working or living near a landfill, one telltale sign of a landfill’s presence is often unpleasant odors. Landfill gases are formed when buried waste decomposes due to microorganisms or volatizes as the waste changes from a liquid or solid to a vapor. ...

Case Study: Odor Abatement Solutions
Odor issues related to industrial processes are not uncommon. An odor is caused by one or more volatilized organic compounds (VOCs) that humans can perceive by the sense of smell. The challenge is that “odor is subjective, and what is sweet to some, can be a nuisance to others. In most cases the compounds that create the offensive odors are not present in sufficient concentrations to ...

Development of on-line and field dual TD-GC-FID/MS for automatic and continuous ambient air and odor monitoring
Ambient air is polluted by many Volatile Organic Compounds (VOCs) coming from anthropogenic and natural sources. VOCs from PAMS, T014 and T015 lists can be measured in many ranges of concentration, from ng/m3 up to mg/m3 depending on the location of the measurements. Due to the large number of molecules, the complete separation of all compounds is difficult to perform using chromatographic ...

V-Bank Transition (VTS) - Robert O. Pickard Environmental Centre, Ottawa, Canada - Case Study
THE PROBLEM: The RobertO. Pickard Environmental Centre (ROPEC) in Ottawa, Canada was undergoing needed upgrades and expansions to its thickening and dewatering building. This building plays a vital role by in water treatment providing sewage receiving and pumping, sludge mixing and thickening, as well as dewatering digested biosolids. These processes release H2S, Ammonia, and other VOC's into ...
