  • Thermally activated persulfate oxidation of NAPL chlorinated organic compounds: effect of soil composition on oxidant demand in different soil-persulfate systems

    This study investigates the interaction of persulfate with soil components and chlorinated volatile organic compounds (CVOCs), using thermally activated persulfate oxidation in three soil types: high sand content; high clay content; and paddy field soil. The effect of soil composition on the available oxidant demand and CVOC removal rate was evaluated. Results suggest that the treatment ...

  • In situ Chemical Oxidation: An Innovative Groundwater Remediation Technology

    A promising new technology, in situ Chemical Oxidation (ISCO), has the potential to supplant the more widely used pump-and-treat groundwater remediation technology by destroying groundwater contamination in situ (in place). ISCO is the process of oxidizing contaminants in the groundwater and soil by injecting water containing high concentrations of an oxidant to the site of the contamination. ...

  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • Biodegradation of MTBE Utilizing A Magnesium Peroxide Compound: A Case Study.

    ABSTRACT: A patented magnesium peroxide compound was recently employed at an underground storage tank facility to increase the available oxygen in the groundwater for the biodegradation of fuel hydrocarbons. The objective of this remedial effort was to substantially reduce the dissolved-phase concentrations of BTEX and MTBE and to arrest further migration of the dissolved fuel hydrocarbon plume. ...

  • Shifting Paradigms of Environmental Management

    Introduction In the past few decades there has been an all around awareness of environmental degradation caused by industrial activities on account of green house gas emissions, stratospheric ozone depletion, acid rain and acidification, eutrophication, soil degradation, technological hazards, chemical mists and fog with potential damage to human race. Environmental considerations therefore ...

  • Ozone in the Laundry Industry - Practical Experiences in the United Kingdom

    Abstract Since the early 1990s, the use of ozone in many commercial and industrial laundering applications has been evolving rapidly. Ozone allows washing to be conducted using cold water, thereby saving considerable heat energy and water consumption. Additionally, ozone enhances the wash process, resulting in a significant reduction in detergent dosage and number of rinses, thus saving ...

  • Composting of a mixture of orange and cotton Industrial wastes and the influence of adding olivemill Wastewater

    The rapid expansion of the agro-industry during recent decades has led to the increasing production of organic wastes. Some such agroindustrial wastes are olive mill wastewater (OMW), the waste from orange juice extraction (OW) and the waste from cotton gins (CW). The OMW resulting from olive oil production contains olive pulp, mucilage, pectin, oil, the vegetable water of the fruit and the water ...

  • Biofilter Applications in the Coatings Industry

    Soaring energy costs and the high cost of ‘end-of-pipe’ pollution control equipment has caused companies and regulatory agencies to re-evaluate ‘unconventional’ means of achieving VOC and HAP emissions control. The coatings industry is an excellent candidate for alternative, unconventional controls, as VOC and HAP reductions have not been as strident as has been the case in many other industries. ...


  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • Nature’s Own - Biofiltration process offers promise of (near) energy-free pollution abatement

    A filter could be described as any substance through which liquid is passed to remove suspended impurities. Although a “biofilter” is actually not a filter, “biofiltration” is on the threshold of finding a market as a compliance solution for air pollution regulations after a number of false starts. Biofilters have long been used as a means for reducing objectionable odors in Germany, the ...


  • What are the treatment options for landfill leachate?

    New contributor to Water/Waste Processing aims to answer readers’ most pressing questions It’s said the United States has 1,654 landfills, handling more than 250-million tons of trash each year. One Washington landfill covers a 2,545-acre area, has a 120-million-ton capacity and a 40-year expected trash-receiving life. The facility, the Republic ...


  • Least-Cost Approaches to Reducing Acid Emissions

    ' The costs of meeting sulfur emission targets can be high. It is essential, therefore, that countries adopt policies which (a) minimize the net economic and social costs of reducing emissions to the agreed target levels, and (b) maximize the overlap between measures designed to reduce acidifying emissions and those addressing other forms of air pollution. This note discusses alternative ...

  • New EEA Report

    Environmental Signals 2000 is the first of a series of regular indicator reports on the European environment to come from the Agency. Published annually, these reports will provide policy makers, experts and the general public with the very latest assessments of the EU’s environment. The reports will fill the five-year gaps between the EEA’s main state of the environment reports such as ...

  • Reducing air pollution from electricity-generating large combustion plants in the European Union

    Background In 2008, the European Environment Agency (EEA) published a first assessment of the theoretical potential to reduce emissions of nitrogen oxides (NOX) and sulphur dioxide (SO2) from electricitygenerating large combustion plants (LCPs) (EEA, 2008). That earlier study showed that improving the environmental performance of existing LCPs by applying best available techniques ...

  • Ecological and Human Health Risk Assessment: Focussing on complex chemical risk assessment and the identification of highest risk conditions

    The mission of the Joint Research Centre, which is a Directorate General of the European Commission, is to provide customer-driven scientific and technical support to the EU policy making process, ensuring support to the implementation and monitoring of existing policies and responding to new policy demands. The way that the Joint Research Centre accomplishes its customer-driven tasks is mainly ...


  • Overview of Airborne metals regulations, exposure limits, health effects, and contemporary research case study

    One of the consequences of the current state of industrialization and an increasing demand for modern conveniences and improved quality of life has been an increased exposure to air pollutants from industrial activities, traffic, and energy production. Regulatory bodies, such as federal, state, and local environmental protection agencies, are responsible for assuring the public that the air is ...

  • Lessons learnt and opportunities in alternative European economies

    Recent headlines highlighting the return of Polish migrants indicate the comparative strength of the zloty against the pound. Peter Reich, of URS Deutschland GmbH, Uwe Senftleben of URS Washington Division, Poland and Toby Uppington of URS Corporation look at the opportunities there. While the UK has been in recession, Poland has just registered modest economic growth of 1.1%. When Poland joined ...


  • Falling Oil Price Forces Operators to Find Cost Savings in Water Management

    When oil prices were 80 to 100 dollars per barrel, water management costs were high, but they were tolerable when money was flowing profitably. However, as today’s falling price nears 40 dollars, water related costs are still high and only exacerbate widespread industry losses. The 150 US-based companies tracked by Oil & Gas Journal and Oil & Gas Financial Journal reported that ...
