20110003350 | SYSTEM AND METHOD FOR HIGH-VOLTAGE PULSE ASSISTED AGGREGATION OF ALGAE - A method and device for aggregating algae in an aqueous solution is disclosed. The method can include providing an algae feed comprising a liquid and algae dispersed therein. The algae feed can be aggregated by applying a nanosecond pulsed electric field to the algae feed. The nanosecond pulsed electric field can include a plurality of electric pulses having a pulse duration ranging from 1 to 1,000 nanoseconds. The method can also include separating an aggregated algae stream from the algae feed and feeding the aggregated algae stream to a lipid extraction operation. | 01-06-2011 |
