Experimental Study on Inactivation of Heterosigma akashiwo by Pulsed Electric Field and Engine Waste Heat Treatment

Abstract:

Ballast water (BW) is essential in maintaining the balance and structural integrity of ships during voyage. However, invasive aquatic species discharged through ballast water is one of the most serious problems posed nowadays in the marine environment. Experimental inactivation effect on Heterosigma akashiwo by combined PEF and engine waste heat pretreatment was studied. Effect factors such as pulsed voltage, electrode gap, pulse width and preheating temperature were explored, and its mechanism of inactivate the Heterosigma akashiwo was analyzed. It was prospected to be effective to inactive the mircoalgae of ships ballast water by combined PEF and engine waste heat so as to obtain a cost-effective BW treatment with minimized environmental impacts.
