  • Oxidative degradation of COD in a Petrochemical facility using Ozone-based advanced oxidation

    The aim of this study was to investigate the use of ozone-based advanced oxidation processes for the oxidative destruction of COD in a petrochemical facility. Several AOP experiments were carried out in order to select and optimise the successful treatment option. A LABO3-AOP pilot unit was used where filtered waste water (COD 1250 ppm) was circulated throughout the AOP reactor and ozone & ...

  • Bottled ozone

    Ozone is very versatile as an environmentally friendly oxidation agent. The spin-off company Oxy3, in collaboration with a research team at Montan University in Leoben, Austria, has managed to come up with a new ozone production method. The aggregate is simple to use and plugs into commonly available oxygen bottles. Ozone can be produced simply by pressing a button, in various concentrations; ...

  • Nitrous oxide is now top ozone-layer damaging emission

    According to new research, emissions of anthropogenic nitrous oxide (N2O) are now causing more damage to the ozone layer than those of any controlled ozone depleting substance and this is projected to remain the case for the rest of this century. The study suggests that limiting N2O emissions could help both the recovery of the ozone layer and tackle climate change. Many ozone-depleting ...

  • NOAA study shows nitrous oxide now top ozone-depleting emission

    Nitrous oxide has now become the largest ozone-depleting substance emitted through human activities, and is expected to remain the largest throughout the 21st century, NOAA scientists say in a new study. For the first time, this study has evaluated nitrous oxide emissions from human activities in terms of their potential impact on Earth’s ozone layer. As chlorofluorocarbons (CFCs), which have ...

  • Ozone Monitoring Alert

    The PSD rules have been updated to enforce the new 8-hour ozone regulation. Additional ambient air monitoring requirements have been added to the regulations. This update can be found in 40CFR52.21 (see footnote to the Table for De Minimis Ambient Air Impacts from Modeling) A new PSD source, which has the potential of increasing their emissions of nitrogen oxides by 100 tons or more, may now be ...

  • Ozone water treatment and Cryptosporidium

    The recent outbreak of Cryptosporidium in the drinking water of the Swedish municipal of Östersund shed new light on the importance of effective water treatment systems. Cryptosporidium is a single cell parasite that lives in the intestines of animals as well as humans and is spread through excrements. It is very hardy and can survive in many different environments. It is often ...

  • Often-overlooked yet potent pollutant nitrous oxide poses Ozone and climate risks, UN warns

    Emissions of nitrous oxide (N2O), an often-overlooked yet potent gas, could nearly double by 2050 and thus potentially undermine gains in the ozone layer recovery and exacerbate climate change. Drawing Down N2O to Protect Climate and the Ozone Layer, a new report by the UN Environment Programme (UNEP), warns that nitrous oxide is now the most important ozone-depleting emission and the third most ...

  • Action needed on ground-level ozone

    Air pollution caused by ground-level ozone will become a serious threat to human health and food security within the next century unless action is taken on a global scale, according to a recent report. Ozone is a significant air pollutant and important greenhouse gas, third only to carbon dioxide and methane in terms of impact on the climate. It is a powerful oxidant that exacerbates conditions ...

  • Why is ground-level ozone not on the decline?

    Europe has significantly cut its emissions of gases that lead to ground-level ozone. Despite this, levels of ozone do not appear to be falling. A recent EEA report questions this and suggests that the effect of the emission cuts on ozone may be masked by variable weather conditions. In many countries of Europe, the time-series of ozone data are yet too short to draw conclusions about long-term ...

  • More effort needed to reduce summer ozone

    Ground level ozone causes health problems, decreases crop yields and damages the environment. Ozone levels exceeding certain targets in Europe were less frequent in summer 2011 than in any year since monitoring started in 1997. However, the long-term objective was exceeded in all EU Member States and it is likely many of them will not meet the target value, applicable as of 2010. "In ...
