The advantages of physico-chemical treatment

Physico-chemical soil treatment is an effective technique to clean contaminated soils, removing a wide range of both organic and inorganic contaminants. Contaminants adhere to the fine-fraction of the soil, such as organic matter and clay/silt. The principle of the method utilizes the difference in grain-size and density of the materials and separates the different fractions by means of ...

China Case Study (In Situ Gas Thermal Remediation (GTR™))

Gas Thermal Remediation (GTR™) was recently used to successfully remediate benzene and chlorobenzene impacts in China. This was the first time in situ thermal remediation was used in the history of Chinese remediation efforts. In partnership with JSDDBS, GEO used its Thermal Conductive Heating (TCH) to remove contaminants from soil and groundwater at 100 degrees Celsius. The final ...

Bioremediation of Naphthalene and Methylnaphthalene Isomers

Petrox bioremediation accelerates the removal of naphthalene and isomers of methylnaphthalene. These petroleum compounds are often slow to remediate due to their low volatility and strong affinity for absorption onto soil particles. The remediation rate of these compounds is slower than BTEX compounds. They often also rebound as the absorbed phase solubilizes following removal of the compound ...

Simultaneous removal of polycyclic aromatic hydrocarbons and copper from soils using ethyl lactate-Amended EDDS solution

A new approach using aqueous ethyl lactate-modified [S,S]-ethylenediaminedisuccinic acid (EDDS) washing solutions was examined in the laboratory for the simultaneous removal of phenanthrene, pyrene, and Cu from contaminated soils. Ethyl lactate demonstrated greater solubilization efficiency for phenanthrene and pyrene than ethanol. Thus ethyl lactate has a great potential for extracting ...
