Abstract: 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.

Abstract: A method and plant for separation of an aqueous dispersion of particles into separated particles and aqueous solution involves using electrocoagulation treatment followed by removing the particles as a flocculated component. The remaining solution is filtered and each filter is cleaned by halting filtration, and sending a reverse flow of cleaning solution, for a predetermined time, through the filter, to dislodge sediment deposited on the filters, when the pressure monitored at the inlet to the filter reaches a predetermined value. The filtered solution may be recirculated as cleaning solution and the solution containing dislodged sediment may be recirculated to be trapped in the flocculated component, allowing for a self-contained self-cleaning system.

Abstract: Method and apparatus for separation of dispersed particles from an aqueous dispersion involves subjecting the aqueous dispersion to electrocoagulation (EC) treatment to promote formation of a flocculate comprising the particles, collecting the flocculate comprising the particles as a flocculated layer floating on a clarified aqueous solution and separating the flocculate from the remaining clarified aqueous solution. An aqueous solution of a gas is blended with the aqueous dispersion of particles, prior to separating the flocculate from the remaining clarified aqueous solution, with the aqueous solution arranged to be supersaturated with the gas on blending with the aqueous dispersion. The blending of the EC-treated aqueous dispersion with the supersaturated solution of gas speeds and facilitates separation of flocculate from clarified aqueous solution.

Abstract: A method and apparatus for applying electrocoagulation treatment to an aqueous dispersion includes flowing the aqueous dispersion through a region comprising sacrificial electrodes between opposed electrodes and applying a voltage across the opposed electrodes to pass a current through the sacrificial electrodes causing donation of cations to the aqueous dispersion. The voltage polarity is alternated at intervals T periodically. Following each reversal of polarity, the aqueous dispersion flow rate through the region between the electrodes is arranged to be in excess of a value F R , for a period T R of at least 0.05T wherein F R is greater than 1.1 F M , wherein F M is the mean flow rate between each reversal. This arrangement reduces oxide build-up on the electrodes and sacrificial electrodes and reduces maintenance requirements.
