Solidification and Stabilization (S/S)
In-Situ Solidification/Stabilization: Enhancing the performance of cement based systems
In-situ S/S treatment can be more cost effective and more protective of human health and the environment than traditional dig-and-haul remedies. In-situ S/S treatment minimizes excavation and the associated release of volatiles and eliminating the additional costs of landfill disposal. Solidification/stabilization (S/S) prevents or slows the release of hazardous constituents from contaminated media. CETCO provides in-situ treatment additives for cement based S/S projects.
Ex-Situ solidification of sludge, soil or sediment: Meeting disposal criteria
To ensure safe disposal of contaminated media in a landfill, waste must meet certain disposal criteria, ensuring that liquid phase materials are properly solidified. CETCO provides ex-situ treatment technologies that can be used alone or as an additive to cement based mixes. These materials are mixed into waste or contaminated media to render it safe for landfill disposal.
Typical sites using CETCO S/S technologies
- Wood preserving sites
- Manufactured Gas Plant (MGP) sites
- Chemical plants
- Oil refinery sludge lagoons
Low-level rad-waste solidification: Meeting waste disposal criteria
Super absorbent media are used to solidify aqueous low-level radioactive waste (LLRW) and mixed waste (MW) generated by DOE, DOD and other commercial facilities. These products have a strong affinity for water. They are capable of absorption ratios of up to 300:1 by weight with minimum swelling. Through a sorption mechanism, water is bound and converted into a high strength gel, which will retain its disposition throughout transportation and final disposal. The use of CETCO super absorbent media over traditional absorbing agents allows generators of LLRW and MW to significantly reduce their cost for disposal by minimizing the total volume.
