Integrated Electrochemical Remediation Technologies

A brief explanation of these integrated technologies is presented in this section. 

Electrokinetic biobarriers (also known as electrokinetic biofences) are modified electrokinetic barrier used to contain and biodegrade organic pollutants in ground- 

Electrolytic reactive barriers (also known as e barriers) consist of closely spaced permeable electrodes installed in a trench perpendicular to the direction of ground-water flow intercepts a groundwater contaminant plume, similar to PRBs. Rgure 

It should be noted that the electrokinetic-chemical reduction principles are the same as electrokinetic-PRB using iron filing as reactive media, but one has to wait for the contaminated water to pass through the PRB for the remediation to occur. 

However, in electrokinetic-chemical reduction approach, the nanoscale iron particles are introduced into the contaminant source zone itself, thereby reducing the treatment time.

Electrochemistry can offer much for solving or alleviating environmental problems. Over the past 15 years, electrochemical technology has been largely developed for its alternative use in wastewater remediation. The strategies include both the treatment of effluents and waste and the development of new processes or products with less harmful effects, often denoted as process-integrated environmental protection. Electrochemistry offers two options for the treatment of these pollutants with the aim of oxidizing...
