Abstract
Lockhart's remarks (1) on our previous interpretation (2) of the electrochemical aspects of the electroosmotic dewatering (EOD) of clay suspensions are analyzed to provide some further clarification. Based on Lockhan's excellent work (1, 3–8), we put forward here novel electrochemical interpretations of some features of the following experimental observations: (i) Galvani dewatering; (ii) The dewatering efficiency: (iii) High voltage needed for dewatering Al-kaolinite and aluminium electrode effect.
