The present study has provided a comparison between a conventional ex situ method for the treatment of contaminated soil, a soil slurry bioreactor, with a novel technology in which a contaminant is rapidly and effectively removed from the soil by means of absorptive polymer beads, which are then added to a two-phase partitioning bioreactor (TPPB) for biodegradation of the target molecule. 4-nit...

Soil with heavy metals’ contamination has caused worldwide concern, and there is an increasing interest in the application of washing agents for remediation soils contamination. The review summarizes recent findings about soil different agents. For technologies, solubilizing capability, toxicity, biocompatibility are essential concerns. Washing can enhance desorption removal from soil. Inorgani...

In this analysis, the economics of MBI International’s three-phase surfactant washing system for the removal of polychlorinated biphenyls (PCBs) from sediment was optimized. The system, which consists of a screw washer, an oil/water separator, and a vacuum filter, transfers PCBs to a sacrificial oil layer through two individual two-phase partitioning steps. At the completion of the washing proc...
