Carbon recovery from screenings for energy-efficient wastewater treatment
The energy content of screenings from six municipal wastewater treatment plants (WWTPs) was examined. Hourly samples of separated screenings were taken over 24 hours at three of the plants to illustrate diurnal variations. To recover the chemical energy, which usually leaves the WWTP with the screenings, a screenings wash press was used to transfer organic matter from the solid into the ...

Comparison of different measurement methods of odour and odorants used in the odour impact assessment of wastewater treatment plants in Poland
The aim of this study was to compare sensory and analytical methods used to measure odour and odorants concentrations for odour impact assessment on municipal wastewater treatment plants (WWTPs). A range of sources and odour or odorants concentrations were used to compare the methods. Four different odours and odorants measurement methods were compared: field olfactometry using Nasal Ranger® ...

Variations of odorous VOCs detected by different assessors via gas chromatography coupled with mass spectrometry and olfactory detection port (ODP) system
Odorous volatile organic compounds (VOCs) were analysed via a thermal desorption gas chromatograph coupled with a mass spectrometer and olfactory detection port (TD-GC-MS/ODP) to characterize odour emissions from a wastewater treatment plant (WWTP). Three trained ODP assessors, screened according to the European dynamic olfactometry standard (EN: 13725), were used for the olfactory analysis. ...

3mm Microbar Screen Louisville, Ohio WWTP - Case Study
The city of Louisville, Ohio installed a 3 mm Or-Tec Blue Whale Microbar Screen in its wastewater treatment plant in November 2018 to screen hair, wipes, plastics and other 'rags' from its influent wastestream. Louisville is a bedroom community with around 10,000 residents and a few light businesses. Its plant is designed to treat up to 6 million gallons of wastewater per ...
