Electro-Osmotic Dewatering at Low Applied Voltages

Another fact that needs comment is the observation by Lockhart that EOD can be achieved even by the application of 1 V to the 

A variety of other plausible electrode reactions could be invoked (some perhaps arising from trace impurities in the clay/water system or corrosion reactions at the electrodes) to account for the existence of EOD at low applied voltages, (e.g., 1 V).
