    Hazardous waste treatment solutions for site remediation

    The contamination of soils as a result of prior chemical production can often be unpredictable and diverse. The majority of such pollutants will require an ex-situ treatment method. Many of our VacuDry units can be used for direct-feeding contaminated soils. To reduce the input amount for thermal treatment, the VacuDry units can also be used in combination with soil-washing plants: In this case, customers only feed the high polluted fractions and screened fines (e.g. below 10 mm), as well as the filter-cake from the soil washing process. However, we are able to handle soil contaminated with mercury, hydrocarbons, PAH, PCB, dioxins, furans, organic-lead compounds and many more. VacuDry plants for on-site ex-situ remediation projects are delivered in a modular design.

  • Solutions for the in-situ soil remediation

    For over twenty years, BioSolve Pinkwater has been used for Surfactant Enhanced Remediation (SER) to mobilize and solubilize residual NAPL[i], facilitating its recovery and disposal. Depending on soil and plume characteristics, Pinkwater solution can reach contaminated zones through deep injection wells or be gravity fed from surface level injection galleries. After desorbing residual NAPL from soil surfaces on contact, Pinkwater then solubilizes the hydrocarbons in an aqueous emulsion, enabling extraction at down gradient recovery wells or trenches.

    Measurement of naphthalene in ambient air to monitor workplace exposure limits & at remediation & Superfund sites

    The Series 8900 Naphthalene Analyzer provides direct measurement of Naphthalene in ambient air. This instrument is utilized in industrial plants to monitor workplace exposure limits and at remediation and Superfund sites. The Series 8900 Naphthalene Analyzer employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Naphthalene and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. Naphthalene is separated from potentially interfering components on the analytical column and elute to the detector for analysis.

    Contaminated Soils with Diesel Fuel and Heating Oils

    Sitelab's UVF-3100D is used to test soil to help investigate and clean up sites contaminated by above ground or underground storage tanks (USTs). Soils can be analyzed for extended diesel range organics (EDRO) or extractable petroleum hydrocarbons (EPH). Results correlate well to confirmatory lab methods.

    MPP water purification systems for groundwater remediation application

    Toxic hydrocarbons in groundwater can be found dissolved in water diffused over the area. At higher concentrations they can be present as DNAPLs (dense non-aqueous-phase liquids) or LNAPLS (light non-aqueous-phase liquids) creating an enduring source of toxic contaminant supply to the water phase.

    ppm Measurement of Oil in Water for the Petrochemical Industry

    Measuring the oil content in water or soil is a specialty of Wilks Enterprise. InfraCal TOG/TPH Analyzers provide on-site ppm measurements to help ensure upstream or downstream wastewater complies with discharge permits to avoid potentially costly fines. There are over 3,000 InfraCal TOG/TPH Analyzers in operation today around the world measuring the oil and grease levels in produced water on drilling platforms, oil content in FRAC water, hydrocarbons in wastewater effluents from refineries, and TPH in soil at remediation sites.
