The well known HARMO conferences are a series of biannual international conferences on dispersion modelling. This year, the 21st International conference on Harmonisation within Atmospheric Dispersion Modelling for Regulatory Purposes (Harmo21) will take place in the Portuguese city of Aveiro the 27-30 September 2022. This always interesting event for air dispersion modellers comes this time with a nice Perk: A Special Session on Modelling Odour Dispersion and Exposure.
Odour modelling for regulatory purposes is a challenging issue. HARMO conferences have been traditionally seasoned with some odour papers from time to time, but to date, there has not been a special session on odour modelling. This time, HARMO steering committee has proposed a Special Session with the title: Modelling Odour Dispersion and Exposure.
The usually active open access journal Atmosphere of MDPI, has just published a new interesting book on Environmental Odour edited by Günther Schauberger, Martin Piringer, Chuandong Wu and Jacek Koziel. This book is a reprint of articles previously printed in other special issues, and it is available to download for free here.
The book, “Environmental Odour”, comprises one review and nine original papers, and it is the follow up of other special editions published in the past, such as this one and this one. For any odour manager interested in staying up to date on this issue, this is a very good starting point.
The British Columbia Water & Waste Association (BCWWA) is a not-for-profit organization that represents around 4,000 water professionals in this province of Canada. This time, the BCWWA are organizing a 1-day course on the issue of odors from collection systems.
This Wastewater Collection System Odor and Corrosion Control - Virtual Classroom will take place the 6th of April. The course has a cost of $429.00 + GST (around 300€), and the last date to register is March 30, 2022.
The 2022 Collections Systems and Odor & Corrosion Specialty Conference of the Water Environment Association of Texas (WEAT) is organized by the Collection Systems Committee and the Odor and Corrosion Management (OCM) Committee of this organization.
Odor and corrosion problems in wastewater collection systems are increasingly important, and that is why these type of events are usually nice spots for operators and odor managers with a need to learn more about this topic.
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.
During the last years, there is a need to plan strategical investments to reduce Wastewater Treatment Plant (WWTP) odour impact, which it is generally carried out by covering and deodourizing the main process units involved.
Odour dispersion modelling software combined to dynamic olfactometry is the standard technique conducted to evaluate the odour impact studies. However, the results obtained by this methodology strongly depend on the emission sources set in the software. Thus, this study is focused on providing a dynamic odour impact assessment using CALPUFF software simulations, calculated under different “what-if” scenarios, providing a new approach to define the calibration of the emission sources.
Chile is now undertaking the preparation of three odour regulations for: Swine's farms, the sea products processing plants and it has started the process of reviewing the emission standard for pulp mills. Carrying out regulatory processes to solve the issue of annoying odours is not an easy job, because it has different characteristics compared to the rest of the atmospheric pollutants.
However, the development of normative processes in Chile has so far provided important learning instances for each of the obstacles that have had to be overcome. Thus, the main objective of this work is to disseminate three lessons learned from the odour standards development processes in Chile. The results of this work are expected to contribute to other normative processes that will be initiated, particularly in Latin American countries.
