Abstract
Described herein are systems, methods, and apparatuses for aggregating microorganism in an aqueous suspension. In particular, are systems, methods, and apparatuses that apply an electrical field to an aqueous suspension comprising microorganisms as the aqueous suspension follows a flow path to cause aggregation of the microorganisms. The electrical field may comprise different types of pulses. In some embodiments, the flow path for the aqueous suspension may vary.
Claims6
A method of aggregating microorganisms in an aqueous suspension, comprising:
- a. providing an aqueous suspension feed comprising a liquid and microorganisms dispersed therein;
- and
- b. aggregating the aqueous suspension feed, the aggregating comprising:
- applying a pulsed electric field to the aqueous suspension, the pulsed electrical field generated by a power source and a pulse generator, wherein said pulse generator produces a preprogrammed or alternating pattern of at least two different electrical pulse types which differ in at least one pulse parameter selected from the group consisting of a pulse amplitude, a pulse duration, a pulse shape, and a pause duration between pulses.
