  • Air pollution at the Bily Kriz mountains in the Czech Republic

    An evaluation of air pollution at the Bily Kriz mountains in the Czech Republic is given. Annual daily concentrations of sulphur dioxide (SO2), nitrogen oxides (NOx), particulate matter of size 10 mm (PM10) and ozone (O3) measured in the years 1994–2000 are presented. Air pollution at Bily Kriz is assessed with ...

  • Air pollution effects on the activity of antioxidant enzymes in nerium oleander and robinia pseudo acacia plants in Tehran

    Air pollution is one of the most significant environmental concerns in both developed and developing cities. The urban air quality is continuously affected by emissions from both stationary and mobile combustion sources. Mobile sources contribute to the emission of major urban air pollutants including: carbon monoxide (CO), nitrogen oxides (NOx), sulphur oxides (SOx), particulate matter (PM), ...

  • Pulsed corona discharge for degradation of aqueous humic substances

    The research into oxidation of aqueous humic substances (HS) with pulsed corona discharge (PCD) was undertaken to estimate the energy efficiency of the treatment. The PCD system consists of a voltage pulse generator and reactor, in which the gas-phase discharge generating OH radicals and ozone treats the water showered between electrodes. The influence of HS initial concentration, pulse ...

  • Highly efficient treatment of industrial wastewater by solution plasma with low environmental load

    Advanced oxidation techniques are efficient processes to dispose of organic contaminants in industrial wastewater with low secondary pollution. The solution plasma technique was featured as an advanced oxidation technique with low secondary pollution and high efficiency. However, the solution plasma technique reported previously could only treat wastewater of less than 200 mL owing to the ...

  • The application of Eulerian models for air quality prediction and the evaluation of emission control strategies in Canada

    The Canadian Hemispheric and Regional Ozone and NOx System (CHRONOS) has been designed for the prediction of atmospheric oxidants on both regional and hemispheric scales. The model simulates dispersion and complex chemistry of nitrogen oxides and volatile organic compounds (VOCs) using inventories of actual anthropogenic emission. The meteorological input for the model is provided by the ...

  • Hot springs swimming pool: Glenwood Springs, Colorado case study

    Ozone Water Treatment, Color Removal and Ozone Purification In 1991, the Hot Springs Pool and Lodge Resort installed a DIN-Standard ozonation system for treating the world’s largest hot springs-fed swimming pool. The following main reasons were responsible for this decision: The suppliers of gaseous chlorine had dwindled down to a single source, as it had become ...

  • Benefits of the CFC Phaseout

    Benefits of the CFC Phaseout The CFC phaseout is already producing benefits for the environment, businesses, and individuals. This fact sheet explains some of these benefits. Several case studies of successful conversions to alternatives are listed also. Protection of the Ozone LayerThe chlorofluorocarbon (CFC) production phaseout is an important turning point in ...

  • Electrochemical degradation of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in groundwater

    Perfluoroalkyl and polyfluoroalkyl substances (PFASs) represent hazardous pollutants and are frequently detected in the environment, e.g. in contaminated groundwater. PFASs are persistent to biodegradation and conventional oxidation processes such as ozonation. In this study electrochemical degradation of PFASs on boron-doped diamond (BDD) electrodes is demonstrated. Experiments were performed ...

  • Utilisation of Methane to Generate Electricity: BHP Appin and Tower Collieries

    Background BHP Collieries Division operates five underground coal mines in and around the Illawarra region of NSW. They include the Appin and Tower mines which are situated north-west of Wollongong and some 75 kilometres from Sydney. These two mines produce around 3.5 million tonnes of coal per year which is primarily used for domestic steel making. Some coking and energy coal is also ...
