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 ...

Identification and characteristic analysis of microorganisms in an integrated bioreactor for odours treatment
Odours containing some hydrophilic and hydrophobic compounds could be efficiently removed by the degradation of bacteria and fungi in an integrated bioreactor. Microorganisms from the integrated bioreactor were observed and identified. The amount, species and distribution characteristics of the microorganisms depended on the properties of the compounds being treated, the concentration and the ...

Treatment of unpleasant odors in municipal wastewater treatment plants
The purpose of this paper to present a case study on how to address the odor problem from secondary sources within a municipal wastewater treatment plant (WWTP) by first identifying the locations of the problem and second by evaluating alternative treatment technologies. The WWTP of Chania is a typical 100,000 equivalent inhabitants-facility in a warm semi-arid environment which is located close ...

Case Study - The performance of the grease degrading bioproduct greasolux in the wastewater treatment plant of the resort town
Problem One of the Lithuanian resort towns, during the warm period of year, continuously had problems with the fat, oil and grease (FOG) accumulation in the sewer lines and wastewater treatment plant. The highly polluted wastewater directly impacted the treatment plant in the following ways: Increased grease accumulation in sewer lines and lift: stations; Poor sedimentation of the active ...

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 ...

Performance of activated sludge diffusion for biological treatment of hydrogen sulphide gas emissions
Odours from wastewater treatment plants are comprised of a mixture of various gases with hydrogen sulphide (H2S) often being the dominant constituent. Activated sludge diffusion (ASD) as a biotreatment system for odour abatement has been conducted for over 30 years but has limited broad application due to disagreement in the literature regarding the effect that ASD may have on wastewater ...

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 ...
