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 ...

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 ...

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 ...

Odour reduction strategies for biosolids produced from a Western Australian wastewater treatment plant: results from Phase I laboratory trials
This study investigated sources of odours from biosolids produced from a Western Australian wastewater treatment plant and examined possible strategies for odour reduction, specifically chemical additions and reduction of centrifuge speed on a laboratory scale. To identify the odorous compounds and assess the effectiveness of the odour reduction measures trialled in this study, headspace ...

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 ...
