  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Ozone Based AOP process for refractory COD reduction in industrial waster water

    Introduction In recent years improvements  in ozone based advanced oxidation technology efficiencies have lowered capital and operating expenses, improving the viability of the use of ozone as the main oxidant. An investigation into alternatives for refractory COD removal which is economically attractive and do not produce sludge lead to an evaluation of ...

  • Hardware Solutions to Monitor Gas and Thermal Energy

    Why Monitor Gas and Thermal Energy? Hang on, are you telling me you are an energy manager that’s only worried about electricity!? Let’s take a step back and realise that gas represents nearly 40% of the total energy consumed in the industrial and service sectors in Europe. That’s almost half, you guys! ...

  • Photodegradation of 4-chloronitrobenzene in the presence of aqueous titania suspensions in different gas atmospheres

    The photocatalytic degradation of 4-chloronitrobenzene (4-CNB) was carried out using Degussa P25 TiO2 as photocatalyst in three different gas atmospheres: nitrogen, oxygen, and ozone. The total organic carbon (TOC) and inorganic anions including chloride, nitrite, and nitrate anions were measured to monitor the mineralization processes, while the degradation of 4-CNB and the formation of ...

  • Biological wastewater treatment followed by physicochemical treatment for the removal of fluorinated surfactants

    Perfluorinated surfactants (PFS) have become compounds of high concern during the last decade. While “conventional surfactants” are degraded to a great extent in the biological wastewater treatment process, partly or perfluorinated surfactants are not only stable against biodegradation but also against oxidizing agents, they even resist OH-radical attacks. Our objectives were to eliminate the ...

  • The effect of pre-ozonation and subsequent coagulation on the filtration of WWTP effluent with low-pressure membranes

    The impact of a pre-treatment by pre-ozonation (2–10 mg O3/L) and subsequent coagulation (FeCl3: 2–6 mg Fe3+/L) on the performance of a polymeric ultrafiltration membrane was investigated in lab scale. The performance was assessed by monitoring the flux decline during filtration of secondary effluent in Amicon test cells. During the filtration process no free dissolved ozone was in contact with ...

  • Air quality in Europe - 2014 report

    Despite considerable improvements in the past decades, Europe is still far from achieving levels of air quality that do not pose unacceptable risks to humans and the environment. Air pollution is the top environmental risk factor of premature death in Europe; it increases the incidence of a wide range of diseases and has several environmental impacts, damaging vegetation and ecosystems. This ...

  • Fixed multi-parameter gas detection system can ensure industrial facilities are safe from hazardous or toxic gases

    Industrial workplaces are likely to come across one or more hazardous or toxic gases. Combustible gases such as methane are highly dangerous because they can cause large and fatal explosions when ignited. Other problem areas when working in industry are carbon monoxide (which poisons the cardiovascular system), oxygen deficiency, and elevated levels of other gases and pollutants, depending and ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...

  • Air pollution in Europe 1990-2004

    Overall picture This report analyses and presents changes in air pollutant emissions and their possible health or ecosystem impacts in Europe covering the period 1990–2004. Emissions of all air pollutants fell substantially during the period 1990–2004 in the 32 EEA member countries (EEA-32), resulting in improved air quality over the region. However, ambient concentrations of particulate ...

  • Some early beginning of global warming, its causes, and how we will yet GREEN our earth

    Global warming is the result of mankind’s greed and selfishness. We have known it was going to catch up with us since I was in college in the early 1950's. We were aware fluorocarbons were destroying the ozone layers, yet we were continuing to dump refrigerants into the atmosphere without regard of how they would destroy the beautiful world God created for us. The Corporations that produced the ...

  • Controlling Bacteria In a Clean Room Environment

    Maintaining the integrity of a cleanroom is a constant battle. The first step to deciding which method, or combination of methods, to employ is to identify the prime sources of contamination. There are three prime sources of contamination through which the integrity of a cleanroom might be breached. First, there is the human element. While many processes might be automated, many situations remain ...

  • Different emission estimates produced by EU bodies/institutions

    EU GHG inventory submission to UNFCCC (EEA and DG Climate Action) The European Union (EU), as a party to the United Nations Framework Convention on Climate Change (UNFCCC), reports annually on greenhouse gas (GHG) inventories for the years 1990 to X-2 (i.e. two years before the current year1) and within the area covered by its Member States. The legal basis for the compilation of the ...
