Remedial technologies

With few exceptions, treatment technologies are limited to some extent by the size of the material that they are able to process. These limitations can apply to the throat of the feed devices, the inner workings of the equipment, the treatment mechanisms, or the process elements. To make these remedial technologies efficient and cost effective, separation techniques are used to make the feed stream uniform... [Pg.171]

Another classification of remediation technologies describes where the action is taking place. Ex situ methods are those applied to excavated soil and in situ processes are those applied to the soil in its original location. On-site techniques are those that take place on the contaminated site they can be either ex situ or in situ. Off-site processes treat the excavated soil in fixed industrial facilities, away from the contaminated site. [Pg.522]

For the estimation of the contaminants uptake rate and consequently the time required for the phytoremediation of a contaminated site, single mathematical models may be applied. In the following paragraphs, analysis as well as the examples given in Groundwater Remediation Technologies Analysis Center Technology Evaluation Report on Phytoremediation, by Schnoor, is presented without modification.8...

This chapter presents a regulatory overview of on-site remediation, remedial investigations (RI), feasibility studies (FS), remedial technologies, and a simulated case study. The discussion of remedial investigations and feasibility studies also includes the development and selection of remedial technologies. The case study outlines a remedial investigation and feasibility study, as well as the selection of remedial technologies. [Pg.590]

The relationship of electrokinetic phenomena and the movement of petroleum constituents is not of high importance however, it can be important for the transport of some solutes related to a remedial technology such as electroosmosis remediation. [Pg.700]

Gas control is required, because the vapor phase of gasoline components in an unsaturated zone can pose a significant health and safety threat. The gas control and safety concern are discussed in another chapter. Some of the remedial technologies presented in subsequent sections of this chapter can also act as gas control measures. [Pg.708]

According to the Federal Remediation Technology Roundtable (FRTR) the factors that may limit the applicability and effectiveness of this technology include the following2 ... [Pg.782]
