Solidification and Stabilization
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.
Our products generate solids to pass the following tests:
- Paint Filter Liquids Test (EPA 9095)
- Slump Test - CSA Test Method A23.25C
- Liquid Release Test (LRT) Procedure (EPA 9096)
- Toxicity Characteristic Leaching Procedure (EPA 1311)
- Leachable BTEX (benzene, toluene, ethyl benzene and xylenes)
- Solids meet Class II (non-hazardous) Landfill Criteria
LIQUISORB®
A line of high efficiency absorbing agents ideally for the absorption and solidification of slurries or high-solids wastewaters. These products contain organic and inorganic components that rapidly absorb and retain large volumes of aqueous matter turning liquid into a solid that passes slump tests. Solids generated are non-leachable and pass TCLP. Products are available in both granular and powder forms.

QUIK-SOLID® super adsorbent polymer
QUIK-SOLID super adsorbent polymer is a solid, granular cross-linked polyacrylate advanced super-absorbent media that rapidly absorbs and retains large volumes of fresh water aqueous solutions. Its absorptive properties are ideally suited for the absorption and solidification of hazardous and non-hazardous waste waters, soils, and semi-solid matter. This high efficiency absorbent is capable of absorbing up to 250 times by weight of aqueous matter and reduces waste disposal costs by minimizing volume expansion to less than 1%.
QUIK-SOLID® 50 super adsorbent polymer
QUIK-SOLID 50 super adsorbent polymer is a custom blend of granular cross-linked polyacrylate super-absorbent polymer and ORGANOCLAY. This high performing product rapidly absorbs and retains large volumes of aqueous solutions, while also offering a hydrophobic component to adsorb low soluble organic matter. The absorptive properties of QUIK-SOLID 50 are ideally suited for the solidification of wastewater, sediments and semi-solids containing organic laden contaminants.
QUIK-SOLID® BOOMS
QUIK-SOLID Booms are a higher performing alternative to traditional cellulose absorbent products that are utilized for hazardous, non hazardous and low level radioactive waste disposal. QUIK-SOLID super absorbent media and a cellulose filler material are packaged in a closed nylon sock to ensure maximum polymer retention and absorbency. The sock can be cut to size and placed in drums, boxes intermodal and other transport containers for solidification of aqueous matter and condensation control.
QUIK-SOLID® MATS
QUIK-SOLID Mats are a high-performing yet lower cost alternative to other absorbent fabric products that are used in the hazardous waste or nuclear waste disposal industry. QUIK-SOLID Mats are made with polyester fabric layers bonded together with a special polyolefin adhesive. The QUIK-SOLID granular absorbent polymer is embedded between the layers of fabric and the entire laminate structure is made of non-biodegradable materials.
