  • Arsenic Removal

    The Arsenic Removal ProcessArsenic, a naturally occurring element, is found throughout the environment; for most people, food is the major source of exposure. Acute (short-term) high-level inhalation exposure to arsenic dust or fumes has resulted in gastrointestinal effects (nausea, diarrhea, abdominal pain); central and peripheral nervous system disorders have occurred in workers acutely ...


  • Chlorinated solvents: methylene chloride and TCE

    Introduction This paper presents the results of a scaled and phased approach to source remediation of high concentrations of recalcitrant chlorinated solvent compounds via soil vapor extraction (SVE) and vapor treatment at a Site in Southern California. Phase I began with refrigerated condensation (C3) in order to achieve high mass removal rates to reduce lifecycle costs and time ...

  • Landfill remediation with refrigerants and chlorinated solvents

    PROJECT DESCRIPTION Between 1979 and 1980, industrial and hazardous wastes were disposed of at the Site in a series of unlined pits, each of which was used for a particular type of waste disposal. It is reported based on evaluations of manifests that approximately 3.4 million gallons of hazardous liquid wastes and between 3,700 and 4,100 tons of solid wastes were disposed of in the pits ...

  • Case study - Chlorinated groundwater treatment

    Overview A Fortune 50 company implemented a remedial project to collect and treat polluted groundwater from a site in Central New York, preventing the mitigation of impacted groundwater from flowing into local waterways. An engineering and construction firm was hired to design and build an effective, efficient groundwater treatment system. Collection of the polluted water would be ...

  • Removal of 17β-estradiol (E2) and its chlorination by-products from water and wastewater using non-imprinted polymer (NIP) particles

    Endocrine disrupting compounds and their chlorination by-products are two classes of emerging contaminants. Surface water and wastewater treatment technologies have limitations in removing these contaminants. This study evaluated the ability of non-imprinted polymer particles (NIP) to remove the endocrine disruptor 17β-estradiol (E2) and its chlorination by-products from water and wastewater. NIP ...

  • Petroleum hydrocarbon and chlorinated solvent case study

    Project Description The site is an active fueling terminal located in Van Nuys, California USA. The site has 1underground storage tanks of petroleum fuel as well as numerous above ground storage tanks for containment of various hydrocarbon and chlorinated solvent compounds. Site Geology Soils at the location consist primarily of interbedded layers of silt, ...

  • New Treatment Technology Targets TOC/DOC Removal at Florida Utility

    Turn on any tap in Palm Springs, FL, and you will get crystal clear water. It has no odor, no metallic taste and compares favorably with most bottled waters. The residents are, quite naturally, very happy with it. Getting clean, refreshing water in Palm Springs was not an easy task. The ground water supply in South Florida typically contains large amounts of total organic carbon (TOC) in the ...

  • Bioaugmentation to Treat Chlorinated Solvents in Fractured Bedrock

    ABSTRACT: An in situ bioremediation pilot study was performed at a former industrial site in New Jersey where groundwater has been impacted by historical releases of chlorinated solvents. The target area for treatment is a fractured, intermediate bedrock zone. The remedial objective at the Site is to treat the groundwater while minimizing the impact of the remedial system on the re-development of ...

  • Case study - Emergency equipment for the absorption of chlorine in hospitals

    Chlorine is a strong oxidant that in normal conditions and in its pure state formsdichlorine, a toxic gas with a yellow-greenish colour formed by diatomic molecules (Cl2) that are about 2.5 times heavier than air and have an unpleasant smell. Among its multiple applications and due to its powerful oxidising nature, it is widely used forwater purificationin sewage treatment plants and as ...

  • Catalytic Carbons Help Remove Chloramine

    Untitled Document Summary: Where chlorine creates high levels of trihalomethanes (THMs), chloramine can be an alternative for disinfecting drinking water. Removing it at the ...

  • Chlorinated solvent soil vapor extraction (SVE) remediation case study 2005

    Project Description An active industrial facility in South Central Los Angeles was impacted by tetrachloroethylene (PCE) and trichloroethylene (TCE; former staging area degreasing) operations as a part of its operations. A phased approach to soil vapor extraction (SVE) remediation was employed: the goal of Phase I was to attain high contaminant mass removal rates with very high VOC vapor ...

  • Comparing electrochemical disinfection with chlorination for inactivation of bacterial spores in drinking water

    Drinking water disinfection techniques without the dosage of chemicals are regarded as more advantageous in terms of costs and practical use. Here we investigated the efficacy of electrochemical disinfection for inactivation of Bacillus subtilis spores – a model microorganism of highly resistant pathogens. The effect of electrochemical disinfection with ...

  • Toxic dissolved and dispersed hydrocarbon removal in industrial wastewater and groundwater treatment and reuse with the Macro Porous Polymer Extraction Technology

    Abstract The trend to more severe discharge requirements and to polluted groundwater treatment pushed by governments and followed by industries goes together with the development of more advanced water treatment technologies. Nowadays these requirements have gained such high standards that one step further to contaminated water reuse becomes attractive, especially in areas where fresh water ...

  • Electrical heating for the removal of recalcitrant organic compounds

    ABSTRACT This paper presents a remediation technology that combines electrical heating of the soil with extraction to achieve removal of vapour pressure sensitive compounds, such as chlorinated solvents, volatile and semi-volatile organic compounds, and heavier hydrocarbons. This technology is commercially known as the Electro-Thermal Dynamic Stripping Process (ET-DSP). As well the ...

  • REMOVING LIMESCALE IMPROVES WATER QUALITY IN POULTRY FARMS

    Water is one of the most important nutrients in poultry production.  About 70 per cent of a bird’s body is made up of water - eggs contain around 65% water. Birds are constantly losing water in egg production, so there is an obvious need for constant replenishment.  Water intake is almost twice the weight of ...
