- 304 - Electrochemical System Degrades PCE in Groundwater -- Alshawabkeh
Release Date: 04/01/2020
An electrochemical system can effectively break down tetrachloroethylene (PCE) in groundwater, according to a new study from the NIEHS-funded Northeastern University Superfund Research Program (SRP) Center. After testing different design parameters to determine the best conditions for degrading PCE, the researchers achieved 86% removal of the contaminant from groundwater sources.
- 290 - Promising Membrane Technology Reduces Chlorobenzene in Groundwater -- Alshawabkeh, Bhattacharyya
Release Date: 02/13/2019
A new Superfund Research Program collaboration has developed a promising groundwater cleanup technology that provides an efficient, low-maintenance method of removing chlorobenzene and other compounds from water. The method integrates electrochemical oxidation, which uses electricity to transform contaminants into non-toxic substances, and membranes containing palladium (Pd), a metal used as a catalyst in many industrial chemical synthesis applications and groundwater treatment.
- 251 - Development of a Sustainable Remediation System to Remove TCE from Groundwater -- Alshawabkeh
Release Date: 11/04/2015
An electrochemical system can effectively remove trichloroethylene (TCE) from groundwater at high flow rates, as demonstrated by researchers at the Northeastern University Superfund Research Program (SRP) Center. They optimized the electrode material and configuration to determine the best conditions to dechlorinate TCE at a flow rate of one liter per minute, which exists in karst aquifers.
- 211 - A New Solar-Powered Approach for Groundwater Decontamination -- Alshawabkeh
Release Date: 07/03/2012
Researchers discover a new treatment combination that delivers a one-two punch to eliminate trichloroethylene (TCE) contamination in groundwater. As an added benefit, the method can be driven by solar power for a greener approach to remediation.
