A process for preparing humic-mineral agent granules is disclosed. Such a process may comprise providing a humic acid-containing material; crushing the humic acid-containing material to obtain first granules; contacting a quantity of water with the first granules, thereby forming slightly wet granules; blending the slightly wet granules for a period of time, thereby forming blended granules; contacting an amount of alkali with the blended granules, thereby forming alkali-treated granules; and mixing the alkali-treated granules at a temperature high enough to melt organic carbon substances in the alkali-treated granules. The resulting product has biologically, geologically, and chemically active properties, and may be applied to the soil alone or in combination with a commercially available fertilizer. Additionally, the resulting product may be used to detoxify solid or liquid waste products.

Methods and systems are provided for two-stage treatment of contaminated particulate material, such as soil, sediment, and/or sludge. The methods and systems utilize a thermal desorption process combined with a smoldering combustion process. The contaminated particulate material is first exposed to thermal desorption at high temperatures (e.g., greater than 150° C.) to form a heated contaminated particulate material. Next, a smoldering combustion process is initiated by introducing a combustion-supporting gas. The combined process can take place in the same or different treatment units. Treating the particulate material with a thermal desorption process prior to a smoldering combustion process enhances the completeness and throughput compared to operating these processes separately.

There are provided processes for treating a residual. For example, such processes can comprise treating a mixture comprising the residual, a peracid or source thereof and an ammonium salt in a reactor, with an electric field, by means of at least one anode and at least one cathode that define therebetween an electrokinetic zone for treating the mixture. Such processes allow for inactivation of at least one type of pathogen in the residual so as to obtain a treated residual.

The present application relates to a novel method for reductive degradation of perfluoroalkyl-containing compounds, such as perfluoroalkyl sulfonates, by activated carbon (AC) supported zero valent iron-nickle nanoparticles (nNi.sup.0Fe.sup.0).

A method of sorbing a PFAS compound from a contaminated sample can include admixing a modified clay sorbent with the sample. The modified clay can include a clay intercalated with a blend of mono-quatemary amine compound and multifunctional-quatemary amine compound having a functionality of 3 or more.

An environmental remediation system includes a contaminate treatment mat assembly to extract contaminates in pore water and sediment. The mat assembly includes a flexible liner and pore water and sediment-penetrating chambers individually anchored to the flexible liner. The anchored chambers include lids that are positioned above the liner and containers below the liner. The system includes a plate subsystem including plate holes. The plate subsystem is configured to have the mat assembly removable attached thereunder, absorb impact forces from a delivery system, translate the impact forces into a driving force applied simultaneously to tops of the lids of all the pore water and sediment-penetrating chambers under the plate subsystem to cause penetration of the containers into underlying pore water and sediment, and simultaneously displace fluid through liner holes of the liner and the plate holes. A method for environmental remediating using the system is also provided.
