Study on Pulsed Electric Field to Treat Microorganisms in Cooling Water System of Power Plants

Fang Zhi,Qiu Yuchang,Luo Yi (Xian Jiaotong University, Xian City, 710049)  
The pulse power technology is feasible to treat organism in cooling water system with pulsed electric fields. It differs from the precious process method of using biocides, whose principle is based on the inactivation of microorganisms by pulsed electric fields when the water flows through the cooling water system. From the experiment it is known that the suppressed time of the microorganisms is depend on the pulse continuous time and pulsed field amplitude or the energy density for the single pulsed electric fields. The treatment of the microorganisms in the cooling water with the repeated frequency pulses under the smaller strength of the fields can obtain the same result as the single pulsed field under larger strength of the fields.
