    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.

    Odor control for remediation

    Helping others clean up the earth by clearing up brownfield remediation odors. Helping others clean up the earth by clearing up brownfield remediation odors. Brownfield remediation consists of removing large amounts of soil that have been saturated with tar, oil or other contaminating substances. Not only dangerous to handle, the disturbed soil is often infused with very unpleasant and in some cases potentially nauseous odors.

    Water Treatment Solutions for Nitrate Removal

    Most nitrogenous materials in natural waters tend to be converted to nitrate, so all sources of combined nitrogen, particularly organic nitrogen and ammonia, should be considered as potential nitrate sources. Primary sources of organic nitrates include human sewage and livestock manure, especially from feedlots. The primary inorganic nitrates which may contaminate drinking water are potassium nitrate and ammonium nitrate both of which are widely used as fertilizers. According to the Toxics Release Inventory, releases to water and land totaled over 112 million pounds from 1991 through 1993.

    In-situ Reduction Technology of Groundwater Remediation Industry

    In-situ groundwater remediation method is based on injection of Fe(0) nanoparticles through application wells directly into the contaminated water. nZVI injection is very fast, reaching significantly lower operating costs compared to commonly used remediation methods (expensive construction of reactive barriers, building of pump&treat stations, excavation of contaminated soil etc.). In comparison to other in-situ technologies a far lower quantities of injected chemical is needed due to high efficiency of the product and thus the time and cost of remediation is reduced.

    Mercury monitoring for on-site remediation

    Fugitive emissions can be a health concern during removal and disposal of mercury-contaminated material at remediation sites. Thus, remediation projects either indoors or outdoors often require on-site, real-time mercury air monitoring with a Tekran 2537. This assures permitted levels are not exceeded during waste processing and human exposure levels are below government regulated toxicity thresholds. Often multiple sites must be monitored continuously. The Tekran 1115 Multi-Port Sampler is the ideal tool for multiplexing the Tekran 2537 for real-time continuous on-site monitoring of mercury fugitive emissions.

  • In-Situ Soil & Groundwater Remediation

    The use of H2O2 to chemically oxidize the contaminants into mineralized products (CO2 , salts, and readily biodegradable organic fragments) offers a number of advantages over these current treatment methods. Benefits of Soil Decontamination by Chemical Oxidation: The reagent used (H2O2) is inexpensive, readily available, and has as its reaction products water and oxygen; The chemistry of the process (Fenton's Reagent) has been known for over 50 years and its applicability to a wide variety of contaminants is well documented; The process is easily applied and controlled; The treatment occurs rapidly, lasting from a few hours to a few weeks; The process produces no by-product wastestreams, and can be tuned for the degree of contaminant removal desired. This allows it to be used synergistically with other technologies such as biotreatment or soil washing.

  • 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.

  • Continuous Monitoring of Groundwater

    The Sorbisense method allows for measuring the average concentration of substances in groundwater over a period of up to 1 month with only one sample.

    The system provides methods for measurements in both unsaturated and saturated zone and provides access to dynamic boundaries of contaminants and more realistic risk assessments. For example, through direct measurements of seepage from contaminants and by continuous measurement of emissions from cropland.
