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 ...

Controlling Odors from Waste Water Treatment Plants
INTRODUCTION In recent years, there is growing public awareness of odors from waste water treatment plants, which mainly stems from the following observed trends: The public is less tolerant of objectionable odors from waste water treatment plants; Many waste water treatment plants have seen residential, commercial, or other developments established near the facility boundaries and fence ...

Monitoring of odors emissions from a large wastewater treatment plant
Abstract Because of complaints related to odors emissions from the large “Seine Aval” wastewater treatment plant (2 000 000 cubic meters/day) located near Paris, an extensive measurement programme has been performed, both by olfactometric and physicochemical techniques, in order to characterize the emissions from each step of the water- and sludge treatment processes, and their ...

Odorous compounds monitoring, olfactometry, human noses? Which option should you choose?
Odors are very distinct air contaminants as they generate nuisances and can affect nearby residents. The factors playing a role in the determination of odor annoyance are: odor concentration and intensity, frequency, appreciation, duration and location. Several solutions are available as sensory approach (dynamic olfactometry), sensor technologies (portable sensors, electronic noses, etc.). In ...

Development of a diagnostic tool: the wastewater collection network odour wheel
The assessment of nuisance odour problems and the application of an effective odour management programme for the associated industrial activity may be achieved using a representative odour wheel and Odour Profile Analysis methodology. The odour wheel is a very useful tool for conducting odour quality control monitoring and developing a constructive dialogue regarding nuisance odours with the ...

Estimating odour impact range of a selected wastewater treatment plant for winter and summer seasons in Polish conditions using CALPUFF model
Odour emission from wastewater treatment plants (WWTP) is a common cause of odour nuisance to neighbouring areas. The analysed object was mechanical biological WWTP designed for 1,200,000 population equivalent. Collection of the samples was carried out in accordance with the methodology described in VDI 3880 and PN-EN 13725 during the rainless weather. Odour concentration measurement was made ...

Noses for Surveillance of Wastewater from Secondary Treatment Plants in Alexandria, Egypt
Intermittent discharges of industrial chemical pollutants into sewers can have a damaging effect on the processes involved in treating wastewater. They are sometimes able to pass through treatment plants and enter into the receiving water, to exert a harmful effect on the environment and possibly pass down a river to the intakes forwater supplies. We evaluated the use of an electronic nose ...

H2S monitoring at Stanford WWTP - Case Study
Overview Odour pollution in the form of Hydrogen Sulfide was a major problem at the Stanford Waste Water Treatment Plant. The city administrators did not have data to identify and correlate with the complaints raised by nearby citizens. Oizom’s odour monitoring solution was deployed with real-time data visualization at the WWTP. Oizom’s partner Metersys were empowered to understand ...

Case study - N°AA3 – Ambiant air monitoring – WWP TRS MEDOR odor monitoring
Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers ...

Investigation of the effects of temperature and sludge characteristics on odors and VOC emissions during the drying process of sewage sludge
Sludge drying is a necessary step for sludge disposal. In this study, sludge was collected from two wastewater treatment plants, and dried at different temperatures in the laboratory. The emission of odor and total volatile organic compounds (TVOCs) during the sludge drying process were determined by an online odor monitoring system. The volatile organic compounds (VOCs) in off-gas were ...
