Method and Apparatus for Treatment of Aqueous Dispersion A method and apparatus for applying electrocoagulation treatment to an aqueous dispersion includes: flowing the aqueous dispersion through a region with sacrificial electrodes located between opposed electrodes, and applying a voltage across the electrodes to pass a current. The voltage is maintained at a value V max when the conductivity of the aqueous dispersion is S min or less and the voltage is allowed to decrease to values less than V max as the conductivity of the aqueous dispersion increases. Electrolyte may be added to the aqueous dispersion at low conductivities to further reduce power consumption. The invention allows the electrocoagulation process to operate automatically, without operator intervention, over a wide range of particulate levels with reduced electrical power consumption. |
