  2. Advanced oxidation process - Wikipedia

    en.wikipedia.org/wiki/Advanced_oxidation_process

    The AOP procedure is particularly useful for cleaning biologically toxic or non-degradable materials such as aromatics, pesticides, petroleum constituents, and volatile organic compounds in wastewater. [5] Additionally, AOPs can be used to treat effluent of secondary treated wastewater which is then called tertiary treatment. [6]

  3. Toxicity characteristic leaching procedure - Wikipedia

    en.wikipedia.org/wiki/Toxicity_characteristic...

    Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...

    In 1982, the Marine Corps discovered volatile organic compounds (VOCs) in several drinking water wells that fed into two of the eight water systems. The sources were traced to tetrachloroethylene (PCE) from a two dry cleaners – one on base, the other off the base and trichloroethylene which had been used in vehicle maintenance on the base ...

    en.wikipedia.org/wiki/VOC_BioTreat

    VOC BioTreat™ is a U.S. patent pending technology for Ramboll Environ. This technology allows for the removal and chemical degradation of volatile organic compounds (VOCs) by piping them into a deep-tank aerated activated sludge wastewater treatment plant, [1] which meets U.S. Environmental Protection Agency (EPA) standards for VOC and hazardous air pollutant removal and can be used for ...

    For instance, higher levels of NH3-N, a common contaminant in ground water, can take several hours of air stripping in order to be properly removed from water. In a recent study, it took 4 hours to for the air stripper to reach an equilibrium of efficiency in removing NH3-N elements, topping off at an 81.9% removal rate.

  7. Soil vapor extraction - Wikipedia

    en.wikipedia.org/wiki/Soil_vapor_extraction

    Soil vapor extraction (SVE) is a physical treatment process for in situ remediation of volatile contaminants in vadose zone (unsaturated) soils (EPA, 2012). SVE (also referred to as in situ soil venting or vacuum extraction) is based on mass transfer of contaminant from the solid (sorbed) and liquid (aqueous or non-aqueous) phases into the gas phase, with subsequent collection of the gas phase ...

    en.wikipedia.org/wiki/Biofilter

    Common uses include processing waste water, capturing harmful chemicals or silt from surface runoff, and microbiotic oxidation of contaminants in air. Industrial biofiltration can be classified as the process of utilizing biological oxidation to remove volatile organic compounds, odors, and hydrocarbons.

  9. Non-aqueous phase liquid - Wikipedia

    In order to determine site-specific characteristics e.g. soil material and water table parameters, drill cuttings and cores can be used. Soil gas surveys can be used as a preliminary screening procedure to determine the extent of contamination due to volatile components.
