remediation containment Applications

  • Disposable soil headspace testing container

    The OVT container is an innovative product and a highly effective tool for the preliminary testing of media/soils that have been impacted by a wide variety of volatile organic contaminants of concern (COC’s). • No preparation or modification needed prior to use in field • Air tight OVT lid has built in sealed sampling ports of varying sizes to accommodate different size OVA probes. • Lids snap together so all samples from one well/boring can be easily grouped together. • Reduced potential for injury to employees due to non-breakable material, lighter carrying weight and no sharp cutting edges as on aluminum foil boxes or use of razor knives; • Lid is recyclable & container is made from an environmentally friendly biodegradable material (corn-based) ; • Disposable container reduces potential for cross-contamination of samples (creating invalid data) due to washing and reusing mason jars from multiple sites; • The OVT cell can be purchased on-line and shipped directly to your office or obtained at a local equipment rental location. • Granted a USPTO patent and accepted by the Florida Department of Environmental Protection-BPSS as an Innovative Technology.

    Abatement and Remediation

    Containment and safety issues are a critical consideration when working on any mold, asbestos, or lead remediation/abatement projects. Improperly contained, the dust and bio-contaminants released can, be very harmful for both on-site workers and occupants in neighboring areas. Exactly how you approach your containment and capture solutions will depend on the individual site’s risk assessment report. If you need help identifying solutions to the issues raised in the report, feel free to contact our customer service department and we can review your options together. In most cases, however, there are four common considerations that will be relevant: -Meeting Containment and Air Change Requirements -Monitoring of Containment Pressure -Sterilization of Filtered Air -Removal of Odors, Mold Spores, VOC’s and other Airborne Bio-Contaminates

    Contaminated Water Filtration

    Industry standard best practices are designed to ensure that all work done on Asbestos Abatement Projects is done to the highest level of safety and risk management. Containment of the generated waste water fibers and debris is critical to proper compliance and worker safety. If these fibers are not captured and contained, they can be very harmful for the environment, on-site workers and the occupants of neighboring areas. Exactly how you approach your containment and capture solutions will depend on the individual site’s risk assessment report. If you need help identifying solutions to the issues raised in the report, feel free to contact our customer service department and we can review your options together. Water from showers at Asbestos Abatement sites is often contaminated with asbestos fibers from washing protective gear and equipment. This water must be filtered prior to discharge into a drain.

  • Monitoring of VOCs in Porewater

    Monitoring VOCs in porewater in the unsaturated zone is now possible.

    Sorbisense regularly offers new options for using the patented Sorbicell, which is used to monitor surface water, wastewater and groundwater.

    The latest is almost as “ground-breaking” as the SorbiCell itself. Until now it has been difficult, if not impossible, to directly monitor for volatile substances in pore water in the unsaturated zone. But the environmental consultancy firm Ejlskov A/S in Aarhus combined the use of Sorbisense sampling equipment with the proven technology of soil water samplers. With this combination, a practical new method is made available, which allows for monitoring the presence of porewater-dissolved VOCs above the groundwater table. This provides a significantly improved basis to define and determine the leaching risk to the groundwater, and thus allows for better and more cost-efficient decisions to prevent the pollution in reaching the groundwater.

    A simple construction with multiple options

    The application uses SorbiCell VOC combined with suction cells, soil water samplers. When installed correctly, and applied with the correct procedures, the suctions cells extract capillary bound water from the soil matrix. The system demands no other resource than a container that is put under vacuum. The vacuum in the container then ensures a flow through of the Sorbicell over a period of time, fx. 2-3 weeks. The method is highly suitable for monitoring a site over longer periods of time.

    Waste recovery for construction industry

    Construction waste consists of unwanted material produced directly or incidentally by the construction industry. This includes materials that may contain lead, asbestos or other hazardous materials. There is increasing pressure on the construction industry to dispose of this hazardous material in an environmentally responsible manner. Tetronics can help alleviate this pressure by providing waste recovery plants to deal with all types of hazardous wastes generated from a construction projects lifespan: from land remediation through to the treatment of APCs from incineration as well as the treatment of asbestos.

  • Surface preparation

    Problem: Removing rust, scale and coatings with grit blasting requires containment and/or clean-up, and those costs can have a significant impact on profitability. For contractors doing environmental remediation – removing asbestos or lead paint, for example – the containment issue is even more critical.

  • Trivol 102 Regeneration

    Trivol 102 Regeneration is a natural based absorbent that will soak up all hydrocarbon spills on land. We have super charged our product with millions of microbes that speed up the biodegradation process. Another special additive helps to naturally fertilize the soil to stimulate plant growth and further remediate the affected area. Trivol 102 Regeneration can be added to Trivol 101 Containment after it has been skimmed from water to dry ground.

  • Sulfide Oxidation with Hydrogen Peroxide (H2O2)

    Sulfide Odor Control Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing sulfur (e.g., coal, gas and oil) being refined into industrial products. For a variety of reasons - aesthetics (odor control), health (toxicity), ecological (oxygen depletion in receiving waters), and economic (corrosion of equipment and infrastructure) - sulfide laden wastewaters must be handled carefully and remediated before they can be released to the environment. Typical discharge limits for sulfide are < 1 mg/L. Sulfide Treatment Alternatives There are dozens of alternatives for treating sulfide laden waters, ranging from simple air stripping (for the low levels present in groundwaters) to elaborate sulfur recovery plants (used to treat several tons per day at refineries and coal burning power plants). There are processes based on biology (using compost filters, scrubbing media, or inhibition/disinfection), chemistry (oxidation, precipitation, absorption, and combination), and physics (adsorption, volatilization, and incineration). Each process occupies a niche which is often defined by the scale and continuity of treatment, whether the sulfide is in solution or is a gas, the concentration of sulfide involved, and the disposition of the sulfide containing medium. However, for reasons relating to convenience and flexibility, chemical oxidation (using hydrogen peroxide) continues to grow in its scope of application. Treatment with Hydrogen Peroxide While other peroxygens such as permonosulfuric (Caro’s) acid, peracetic acid, and persulfates will oxidize sulfide, their use for this application is overkill. Hydrogen peroxide (H2O2) is considerably simpler and more cost-effective. H2O2 may control sulfides in two ways, depending on the application: Prevention - by providing dissolved oxygen which inhibits the septic conditions which lead to biological sulfide formation; and Destruction - by oxidizing sulfide to elemental sulfur or sulfate ion.
