MSE offers years of service, hands-on expertise, and resources to test and evaluate technologies to help clean up contaminated sites, soil, and water. We have screened and tested hazardous waste and offgas treatment technologies since 1995, and have found unique, cost-effect solutions to replace incineration as a waste treatment method.
Over the last few decades, promising environmental remediation technologies have been tested to address complicated technological concerns. But the risk of advancing technologies to the field without engineering scale-up testing and ground truthing can be a serious problem. Intermediate engineering scale-up of alternative solutions or studies is critical to resolving scale-up issues. MSE provides an intermediate-scale test facility and houses a number of large-scale components that compliment follow-on facilities to conduct scale-up testing of environmental processes. We have completed successful projects from laboratory scale and progressing through intermediate scale to field implementation. Successful projects include soil and groundwater projects involving Mercury, treatments for the deep vadose zone, Zero Valent Iron (ZVI) barrier repair, Technetium (99Tc) Ion Exchange Skids, and waste processing projects involving sorbent testing.
We offer the following services:
Secondary Waste Form Testing - Engineering-scale demonstration for production of Ceramicrete and DuraLith materials. Project Description
Mercury Ion-Exchange Skid for Building 4501 Sump at ORNL – An ion-exchange mercury treatment skid was designed, fabricated, and installed by MSE in the basement of Building 4501 at the Oak Ridge National Laboratory (ORNL). The skid has treated over 3M gallons of water with 99% mercury removal efficiencies. Integrated studies at the bench scale were conducted to determine specific engineering parameters associated with the technology prior to the skid design and development.
Methyl Mercury in Fish Study for ORNL – a 4-year study at both static and continuous flow was undertaken to elucidate the mercury methylation process in contaminated sediments in East Fork Poplar Creek and test treatment methods to reduce methyl mercury accumulation in fish tissue.
Conceptual Design for a Stannous Chloride Mercury Treatment Skid for Location at Outfall 200 at the Y-12 Plant–Three conceptual designs were submitted for a mercury treatment skid that would treat the water at Outfall 200 at the historic Y-12 Plant. The contract to perform additional bench-scale testing plus design and build a pilot-scale treatment skid followed by a full scale-treatment skid is in the process of being finalized.
Mercury Soil Treatment at Oak Ridge Building 81-10 – MSE combined DOE developed ceramic cement formulations with a mercury treatment reagent incorporated for a jet grouting process to use as a soil grouting and chemical stabilization technology for deployment in the subsurface at Building 81-10 at the Y-12 Plant. Numerous combinations of the material components were tested at the bench scale to determine the most effective combination of components for both injection and stabilization. This combination was tested at intermediate-scale by the use of jet grouting in the subsurface at the MSE Test Facility. The jet grouted volume was excavated to analyze the emplacement of the grout mixture.
Deep Vadose Zone – MSE performed testing for the application of foam as a delivery system for treatment amendments to the deep vadose zone. Pacific Northwest National Laboratory (PNNL) developed the foam formulations, and MSE tested the different foam formulations in two-dimensional boxes to determine proof of concept. Intermediate-scale testing continues.
Zero Valent Iron (ZVI) Barrier Repair – MSE performed bench-scale testing to characterize several different ZVIs. The most effective of these materials were further tested at intermediate scale in both a radial flow apparatus and long columns to determine the effects of several injection parameters. This knowledge was applied during the field-scale application of the technology for repair of the In Situ Redox Manipulation Barrier at the 100-D Area of the Hanford Site (post-injection testing (geophysics and groundwater analysis) was performed after installation of the barrier). Additional geochemical and column injection testing is ongoing for different ZVI products.
Technetium (99Tc) Ion Exchange Skids – MSE performed bench-scale ion-exchange resin testing to determine which resin would provide superior 99Tc removal. MSE then designed, fabricated, and installed two temporary 99Tc ion-exchange skids that were effective at removing the 99Tc from groundwater.
3100 Cubic Meter Project for the Idaho National Laboratory (INL) – Ten commercially available sorbents were tested to determine the superior sorbent material to sorb free liquids for inorganic sludge wastes from the Radioactive Waste Management Complex at INL. This project helped INL achieve the project milestone ahead of schedule.
Fernald Sorbent Study – Several commercially available sorbents were tested to determine a superior sorbent capable of sorbing the free liquids associated with the grouting of Silos 1 and 2 waste ore at the Fernald Site. Two sorbent materials were identified that were capable of sorbing the free liquid. One sorbent material was used to sorb the free liquid in the waste casks and then the waste casks were able to be shipped to Waste Control Specialists in Texas for ultimate disposal.
F-Canyon PUREX – Three commercially available sorbent materials were identified by the Savannah River Site (SRS) for MSE to test for the solidification of F-Canyon PUREX waste. In all, 10,000 gallons were successfully solidified and shipped to the Nevada Test Site for disposal.
