Removal Of Chromium From Groundwater Using Permeable Barriers: An Aquifer Simulation Study
Previous efforts to remediate groundwater contaminated by chromium-bearing industrial wastes have involved post-extraction methods, whereby groundwater is pumped to the surface treated...

Recovery of Chromium from Spent Plating Solutions by a Chromyl Chloride Process
A novel chromyl chloride process has been investigated for the recovery of hexavalent chromium from spent plating solutions. In this process chromium is converted to chromyl chloride by...

Cleaning Up Chromium
From 1956 to 1985, the United Chrome Products plant in Corvallis, Oregon, took a steady toll on the environment. Leaky plating tanks and the discharge of rinse water into a disposal pit...

Chromium Removal by Activated Sludge
The behavior of chromium (Cr) in a laboratory-scale, activated sludge process was evaluated. Both pH and the oxidation state of Cr were confirmed as critical parameters for evaluating...

Fixation of Chromium and Cadmium from Electroplating Waste Sludges
The authors compare the effectiveness of two fixation techniques, namely silicate-cement and lime-fly ash, for immobilizing chromium and cadmium in a waste sludge obtained from an electroplating...
