Continuous Flow Process For Recovery Of Metal Contaminants From Industrial Wastewaters With Magnetic Nanocomposites, David Hutchins

Graduate Theses & Non-Theses

Remediation of metal-containing industrial effluents presents both a technical challenge and an economic opportunity. Many industrial waste streams contain low levels of metal ions requiring treatment prior to discharge. Existing treatment technologies are frustrated by disparate compositions and low metal concentrations. Chemical precipitation is effective; however, it requires excessive reagents and discourages selective recovery. Ion-exchange enables recovery, but requires a batch process with extensive operational and maintenance demands, and is rarely implemented in large-scale applications. A continuous flow process capable of selective recovery would present many advantages over existing technologies.

This research examines and develops a continuous flow process for …
