Chemical remediation technologies

Environmental pollution remains one of the most serious world problems. Great efforts are made to limit release harmful compounds into environment, and a variety methods for remediation soil, surface water, groundwater have been developed over years. Chemical technologies great interest since they can remove degrade pollutants in contaminated sites. This paper focuses on several chemical technologies, such as precipitation, flocculation, adsorption ion exchange, oxidation, soil washing flushing, electrokinetic remediation. Remediation almost always combined with another, although be used separately. Choosing an appropriate technology will depend type site conditions, it should done manner so that cost-effective efficient is chosen. Even though some full-scale, research focused enhancing existing, developing new technologies.
