Abstract
An electrolytic filtration method and apparatus for the concentration and collection of suspended particulates from aqueous solutions is disclosed. The electrolytic cell contains at least an anode and a cathode, and in one embodiment contains a plurality of anodes and cathodes. The electrolytic cell also contains a filter, and in one embodiment the filter is a moving belt filter. While not bound by theory, the electrolytic filtration method and apparatus is based on the electrophoretic movement of algae particles suspended in an aqueous solution away from the filter under the influence of an electric field. In one embodiment the electric field is a pulsed waveform with unidirectional voltage or current pulses. In another embodiment, the electric field is a pulsed waveform with bidirectional voltage or current pulses.
