  • Operating Principle of an Oxygen Monitor

    The oxygen concentration in the flue gas of a combustion process such as that of a power plant or a waste incinerator gives a good indication of the efficiency of the combustion process. The parameter is therefore of great interest to optimize fuel economy, but also to control and reduce emissions of air pollutants. An ideal combustion process only results in CO2 and water, but ...

  • Water Pollution

    Water pollution is a major global problem that requires ongoing evaluation and revision of water resource policy at all levels (from international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. In addition to the acute problems of water pollution in ...

  • Bioremediation of pollutant-contaminated water

    Raw water resources in Kafr El-Sheikh Governorate are affected by many contaminants particularly during the winter season and low demand period of the Nile River, in which water level decreases and organic matter increases resulting in decreased dissolved oxygen, and increased ammonia, nitrite and bacterial load in the water. In this study, physicochemical and microbiological characteristics ...

  • Hazardous water pollution in China

    The people of the Sahecun village in China are currently suffering severe health problems due to dangerously hazardous water. The water pollution has been caused by heavy metal, which is a result of a lead mine that closed down more than ten years ago. Villagers of Sahecun are experiencing dreadfully painful swellings all over their bodies. The heavily polluted water is also causing all kinds of ...

  • Chemical Pollutants in Water Emerge

    Recent advances in contaminant identification methodologies, sampling instrumentation, and analytical chemistry have caused an explosion of knowledge about the presence of previously undetected organic micropollutants. While it doesn’t follow that the mere presence of chemical contaminants results in harm, public health experts, regulators, and others aren’t sitting idly ...

  • Atlas of America`s Polluted Waters

    The maps in this atlas depict the waters within each state that do not meet state water quality standards. States listed these waters in their most recent submission to EPA, generally in 1998, as required by section 303(d) of the Clean Water Act. This provision of the Clean Water Act requires a “Total Maximum Daily Load” or TMDL for each listed water. There are more than 20,000 such waters ...

  • Radiation treatment of polluted water and wastewater

    “Over 70 per cent of the Earth's surface is covered with water, but less than 3 per cent of that is freshwater — most of it locked up in glaciers, ice caps, the atmosphere and deep groundwater reservoirs.Just 13 per cent of the globe's total fresh water is readily available to meet human needs. In themeantime, worldwide demand for water is doubling every 21 years, according to the FAO. ...

  • Transboundary Pollution

    All pollutants can be transported through the aquatic environment and atmosphere, and many accumulate in downstream water bodies and their biota. The probability that pollution will cause transboundary impacts depends on the location of its source in relation to national boundaries, as well as the time it takes for a given pollutant to degrade. In general, microbial pollution is primarily a local ...

  • Water pollution · Canarina DESCAR software

    Natural waters contain micro-organism as well as solutes. There is a distinction between ‘pure’ water, meaning water that is fit to drink and pure water that is a single substance. A water pollutant is a substance that prevents the use of water for a specified purpose. The signs of polluted water are obvious. Poor drinking water tastes and smell bad. ...

  • What are the biggest sources of water pollution?

    Water pollutants can come in many different forms and can have dramatic impacts on fragile ecosystems and aquatic life. There are a huge number of different sources of pollutants and each can have very different levels of harmfulness and environmental impact. In order to explain this further this article explains why water pollution is such an issue,as well as some of its main ...

  • Optimising the Rehabilitation of polluted Mine Tailings and Water by SupaZorb

    To date the polluted acid mine drainage (AMD) – the second biggest environmental problem of the world - from South Africa’s gold mines, was characterised and treated by the precipitation of heavy metals with lime and sulphates, by means of iron exchange. The chemical treatment with expensive and toxic caustic soda (Sodium Hydroxide, NaOH) is to lift the pH, in order to reduce the corrosion on ...

  • Phytofiltration of water polluted with arsenic and heavy metals

    This article reviews recent advances in phytofiltration of arsenic and toxic heavy metals from contaminated water ecosystems. Arsenic and metal contamination in drinking and non-drinking water has created global environmental health concerns. Phytofiltration using aquatic and terrestrial plants has promising potential for the ex situ and in situ clean-up of these waters. An arsenic ...
