  • Horizontal Remediation Well Systems

    Horizontal wells are a proven and effective remedial technology for site cleanup. For environmental applications, horizontal wells offer several advantages in comparison to traditional vertical wells. The first horizontal wells were installed using a mid-sized directional drill rig in 1993 by Directional Technologies, Inc. The three (3) horizontal Soil Vapor Extraction wells installed at John F. Kennedy International Airport was the beginning of a new industry. Directional Technologies, Inc. founders transferred their experience from the oil fields to the environmental industry. This has resulted in the installation of over 1,000 horizontal wells for site remediation worldwide. Horizontal Remediation Wells are a time-tested and proven technology that can provide solutions for problems previously considered unfeasible.

  • Remediation data management

    In most companies today, managers are overwhelmed with poorly organized, de-centralized data and are still making decisions by reacting to historical results driven by non-standardized processes and guessing about the future. Highly customized spreadsheets, manual extracts from hard to use ERP systems, “cut & paste” reporting…sound familiar?

  • 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.

    Water Treatment Solutions for Uranium Removal

    AdEdge provides treatment systems for for Uranium removal using AD92 an anion exchange media that is ideal for use in potable water as well as non-potable and environmental remediation applications for removal of naturally occurring uranium. The high efficiency AD92 can selectively remove the negatively charged uranium anion (most often in the form of uranyl carbonate) to below the existing EPA MCL of 30 ug/L. The AdEdge AD92 systems can deliver the needed performance in two ways: (1) via regeneration type systems which use the media to remove the uranium with periodic regeneration using NaCl brine; or (2) as a “throw away” discardable media, which can be discarded when spent. This option maximizes the very high capacity of the AD92. Where on-site regeneration is not available, this disposal option is the preferred option. Disposal options will vary based on federal, state, and local regulations.

  • 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.
