Part I: Organoclays Improve Performance of Pump and Treat Remediation Systems
|
From Biomin, Inc.
The so-called pump and treat method has been used quite extensively for the remediation of contaminated ground water. Now it is perceived by some in the field as too expensive when compared to newer in-situ methods for the removal of organic compounds. Examples of these are bio-remediation, in-situ oxidation and surfactant injection. It has been found, however, that pump and treat can be economically acceptable and competitive when organically modified clay is combined with the activated carbon used in the conventional version of the system.
