Diversified Technologies' Algae Predator Control System Employs PEF Processing Instead of Chemicals Diversified Technologies, Inc. is developing a new PEF (pulsed electric field) system that offers a non-chemical solution to algae predator control and cellular product extraction. Diversified Technologies' PEF System applies 1 to 20 µs very high voltage pulses that create a 1 to 50 kV/cm high voltage field across a liquid that induces electroporation of cell membranes in microbes, plant, and animal cells. Depending upon the desired effect, PEF voltage intensity lyses the cell membranes in plant cells or can selectively kill predators in predator control, while having little impact on the microalgae cells themselves. http://www.marketwired.com/press-release/diversified-technologies-algae-predator-control-system-employs-pef-processing-instead-2184536.htm
