  • Real Time TOC Analysis in Steam and Condensate

    Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- ...

  • How To Handle Chemical Spills & Cleanups

    FAST-ACT is designed for liquid and vapor chemical releases, but the chemicals it attacks does not need to be limited to what we traditionally think of as a chemical spill. Toxic and noxious chemicals can come from a variety of sources such as waste water, decomposition, household chemicals, and animals. Since FAST-ACT can be applied to liquid spill or vapor release enabling Emergency Responders ...

  • Waste water plant struggles with contamination case study

    A plant in the southwest US commissioning a wastewater plant utilizing proprietary technology for the removal of benzene, toluene, and xylene, or BTX, was experiencing challenges with throughput and elevated operational costs due to the presence of particulate contaminants. The plant takes the wastewater and processes it, removing the BTX prior to being fed to the conventional wastewater plant. ...

  • Geostatistical Methodology For Waste Optimization Of Contaminated Premises

    Summary At the end of process equipment dismantling, the complete decontamination of nuclear facilities requires the radiological assessment of residual activity levels of building structures. As stated by the IAEA: “Segregation and characterization of contaminated materials are the key elements of waste minimization”. From this point of view, the set up of an ...

  • Geostatistical Sampling Optimization and Waste Characterization of Contaminated Premises

    Abstract This methodological study presents a geostatistical approach suitable for radiological evaluation in nuclear premises. By modelling the spatial continuity of activities, geostatistics provide sound methods to estimate and map radiological activities, together with their uncertainty. The main geostatistical principles are first recalled and illustrated on a real premise ...

  • Innovations in the Remediation of Contaminated Sites

      Discussion of the EPA publication completed North American Innovative Technology Demonstration Projects; share the information from this new document which is now available in an online. Mention some of the ongoing and completed field demonstrations of innovative remediation technologies sponsored by EPA and other government agencies such as DOD, NPS, USFS, and BIA. The remediation ...


  • Studies on Biofiltration of Contaminant Mixtures

    Most gaseous emissions from waste water treatment plants, industrial operations, and solids handling facilities, consist of contaminant mixtures rather than pure chemicals. In the literature, several studies have been conducted on biological treatment of gaseous emissions using either naturally bioactive media (soil, peat, compost, etc.) in biofilters or synthetic support media in biotrickling ...

  • Liberating contaminants for easy recovery

    The number one challenge associated with most site remediation designs and methodologies is that 90-95 per cent of all environmental contaminants are present in an adsorbed phase onto soil and bedrock surfaces within both saturated and unsaturated zones. Contaminants, including hydrocarbons (LNAPL), chlorinates (DNAPL) and heavy metals, are sorbed onto the substrates and so have reduced mobility ...

  • Composition and Contaminant Loads of Residual Household Waste Part III: Physico-Chemical Properties and Contaminant Concentrations

    Abstract. Physico-chemical properties of residual waste are key factors for disposal standards. Reliable input data for treatment plants (MSWI) need to consider the heterogeneity and variability of waste composition. This requires thoroughly designed sampling schemes, a consistent separation of bulk waste into uniform fractions, and adequate methods for sample preparation and analysis. The ...

  • Bioremediating Explosives Contaminated Soil

    From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...
