New Special Issue "Odour in Ambient Air" on Atmosphere journal

The open-access journal Atmosphere (ISSN 2073-4433, IF 3.110) has announced a new Special Issue entitled "Odour in Ambient Air". Dr Martin Piringer, Prof. Dr Günther Schauberger and Dr. Wenjing Lu serve as Guest Editors for this issue.

The submission deadline is 10 February 2023, although papers will be published on an ongoing basis from now until that date.

GRAL Dispersion Model has a new website

Since this month November 2022, GRAL dispersion model presents a new website: https://gral.tugraz.at/ The Graz Lagrangian Model - GRAL - was initially developed in 1999 at the Institute of Thermodynamics and Sustainable Propulsion Systems at Graz University of Technology.

In addition, new features and bugfixes have been implemented in the new GRAL Version 22.09, which is now available on the GRAL homepage.

9th IWA Odour and VOC/Air Emissions Conference

As you probably know, Olores.org organized the 9th IWA Odour & VOC/Air Emission Conference will take place the 26-27 of October 2021 in Bilbao, Spain. The IWA Odour and Air Emissions Conferences is one of the worldwide leading odour conferences. These events bring together engineers, scientists, researchers, students, local authorities, managers and other professionals in order to address and discuss emerging odour issues.

More than 160 people attended that event, from 19 different countries, and more than 50 presentations were shown there. Although this conference was held primarily in English, some of them are in Spanish, but you could read their abstract in English..

Saying that, we are very happy to share with you the articles of their presentations, and the videos and PPT files of the ones that have given us their authorization to publish them.

Enjoy the reading!

Standardization of citizen science methodologies for odour nuisance notifications

The initiative is born from the need to create bridges of open, continuous and standardised communication between citizens, administration, companies and universities. This communication will be based on citizen data that will help to better diagnose and observe the activities that are potential odour emitters. The aim of this initiative is to standardise and establish a methodology to identify and diagnose the problem of odour impact through citizen science.

This standard is addressed to citizens, Activities Potentially Generating Odour Impact (APGOIs), administrations, universities, odour experts or other organisations involved in odour management, Universities, odour experts or other organisations involved in odour nuisance management such as NGOs or civil associations.

An innovative wireless tool for off-gas emissions and oxygen transfer efficiency assessment in WRRFs aeration tanks

Water resources recovery facilities (WRRFs) are sources of direct emissions of greenhouse gases (GHGs) and volatile organic compounds (VOCs) produced by biological processes and indirect GHG emissions due to the energy consumed to operate the plant. The direct emissions also contribute to odour issues of WRRFs. Aeration of the biological tanks accounts for 50-60% of the total energy consumption of a WRRF and is therefore the major source of indirect GHG emissions.

The optimized management of oxidation processes is consequently associated with environmental and economic benefits. The innovative solution proposed in this study consists of an automated self-moving prototype (LESSDRONE) for real-time monitoring of oxygen transfer efficiency (OTE) and of GHG emissions from the aerated tanks during operation, and a protocol for converting LESSDRONE measures and specific WRRF data into actions aimed at minimizing carbon footprint (CF) and energy demand.
