Dynamics of nitrogen oxides emission from a full-scale sludge liquor treatment plant with nitritation
Biological treatment in wastewater treatment plants (WWTPs) is a source of nitrogen oxides (N2O, NO and NO2) emitted to the atmosphere. Aerobic ammonia-oxidising bacteria (AOB) have been suggested to be the main source of these emissions. In a full-scale sludge liquor treatment plant at Sjölunda WWTP, it was shown that significant emissions of N2O, NO and NO2 do occur. The plant is operated with ...

Nitrous Oxide 300 Times More Harmful than Carbon Dioxide
Wastewater treatment choices can reduce emissions of the potent greenhouse gas The harmful effects of carbon dioxide on the atmosphere are well known, but another greenhouse gas, nitrous oxide, does considerably more damage to the environment. Many human activities, including wastewater treatment, release nitrous oxide into the atmosphere. This is particularly alarming in light of a 2020 study ...

Report on carbon sensitive urban water futures
The challenge of supplying water and energy required for food production and development while mitigating climate change and adapting to its consequences has been termed the Energy Water Nexus. Water, energy, greenhouse gas emissions and climate change are interlinked through a series of relationships. The water sector is a significant contributor to greenhouse gas (GHG) emissions through several ...

The Crucial Need for Measuring Nitrous Oxide (N2O) Emissions from Wastewater Treatment Plants
Wastewater treatment plants are indispensable infrastructures for maintaining public health and environmental quality. However, these facilities are not only responsible for purifying water; they also emit significant amounts of greenhouse gases, including nitrous oxide (N2O). Despite its potency as a greenhouse gas, the monitoring and measurement of N2O emissions from wastewater treatment plants ...

Centralized water and wastewater treatment as a greenhouse gas producer in Finland
Centralized water and wastewater treatment are key components of modern society but, at the same time, sources of greenhouse gas emissions. In this study, we carried out an assessment of the role of centralized water and wastewater treatment as a greenhouse gas producer in Finland, based on the existing literature and a questionnaire study. The aim of the study was to outline the significance of ...

N2O emissions from a one stage partial nitrification/anammox process in moving bed biofilm reactors
Nitrous oxide (N2O) emissions from wastewater treatment are getting increased attention because their global warming potential is around 300 times that of carbon dioxide. The aim of the study was to measure nitrous oxide emissions from one stage partial nitrification/anammox (Anaerobic Ammonium Oxidation) reactors, where nitrogen is removed in a biological way. The first part of the ...

Wastewater Treatment Plant Monitors Greenhouse Gas Emissions - Case Study
Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

VOC emissions generated from wastewater treatment basins in refineries and petrochemical plants - how to treat them
The challenge Wastewater treatment basins represent a major challenge at an environmental level, since they emit Volatile Organic Compounds (VOC) emissions and generate odours due to the degradation of organic matter, which affect both people working at the plant, as well as the communities around and the environment. Whenever wastewater basins are open to the atmosphere, odorous emissions of ...

Potential of nitrous oxide recovery from an aerobic/oxic/ anoxic SBR process
Nitrous Oxide (N2O) is a kind of greenhouse gas which has a great influence on the global warming. And it is also a powerful oxidant in combustion reactions, which can improve the output power of biogas power generation from 5.7% to 7.3%. It is generally known that the amount of N2O emitted from wastewater treatment is 3% of the total global emissions of N2O. So it is of great significance for ...

Researchers Study GHGs in Winery Wastewater Treatment with DX4015 Gas Analyzer
A research conducted in Southern European wineries compared the conventional and natural wastewater treatment technologies via life cycle assessment and carbon footprint studies. The research group utilized Gasmet’s portable FTIR gas analyzer DX4015 for monitoring the GHGs. The present study can be seen as an important link in helping the wine sector contribute to the fight against the ...

Responses to Internet misinformation
How do people figure out what is accurate and what is not? Science, involving diverse researchers reviewing data and repeating experiments, is the basis for understanding reality. Biosolids recycling has been the subject of such science. And we point to that science on our website, letting our readers decide. Recent Internet postings by Joseph Mercola, David Lewis, and others* - who imply ...
