  • Aerobic and Anaerobic Bioremediation of 1,2-Dichloroethene and Vinyl Chloride

    ABSTRACT: This paper presents a comparative study of aerobic and anaerobic bioremediation of 1,2-dichloroethene (DCE) and vinyl chloride (VC), and includes laboratory bench scale testing of anaerobic biodegradation and a side by side field pilot test comparing the effectiveness of aerobic and anaerobic biodegradation processes. Manufacturing activities at an industrial facility in Ohio resulted ...

  • Aerobic and Anaerobic Bioremediation of cis-1,2-Dichloroethene and Vinyl Chloride

    ABSTRACT This paper presents a comparative study of aerobic and anaerobic bioremediation of cis-1,2-dichloroethene (DCE) and vinyl chloride (VC). The study includes laboratory bench scale testing of anaerobic biodegradation followed by a side by side field pilot test comparing the effectiveness of aerobic and anaerobic biodegradation processes. Prior to initiating the pilot test, DCE and VC ...

  • Biodegradation Tests for Wastewater Samples

    Biodegradation Tests for Wastewater Samples Biodegradation tests usually involve comparison of the oxygen uptake of a test sample – or gas production for anoxic or anaerobic tests – to that for a readily biodegradable control substrate (usually acetic acid, ethanol, or aniline). While biodegradation characteristics can vary among chemical types and wastewater sources, typical patterns are shown ...

  • Case Study: Manipulating Groundwater Redox Conditions for MTBE Remediation

    A pilot study was conducted to investigate the potential to foster anaerobic methyl tert butyl ether (MTBE) biodegradation. The pilot test site, located on Long Island, New York, is characterized as a glacial out-wash aquifer with a high groundwater velocity over 2 ft/day. The MTBE plume is typical of similar plumes that have quickly migrated in this glacial out-wash aquifer. It is ...

  • Application of batch tests to assess antibiotic loads in anaerobic processes

    The presence of antibiotics in drinking water and wastewater has not been widely studied because the sanitary engineering sector mainly focuses on the removal of organic matter and nutrients. There is a lack of environmental regulations for pollutants like antibiotics. Batch tests analyse biodegradability to measure the anaerobic degradation potential of the substrate, or they can be used as ...

  • Characterisation of the recalcitrant organic compounds in leachates formed during the anaerobic biodegradation of waste

    This study investigates the use of UV absorption and fluorescence spectroscopy to assess the early development of recalcitrant organic compounds in leachates formed during the anaerobic biodegradation of municipal solid waste. Biochemical methane potential tests were carried out on fresh waste (FW) and composted waste (CW) over a period of 150 days and leachates produced from the degradation of ...
