Abstract
This article analyzes the theoretical foundations, technological process, and energy efficiency
of wastewater disinfection using pulsed electric field (PEF) technology. The advantages of PEF
technology are considered along with traditional methods of destroying bacteria, viruses, fungi,
and other pathogens in wastewater (chlorination, ozonation, ultraviolet radiation, and membrane
filtration). The study shows that exposure to high-voltage short pulses induces electroporation in the
cell membrane of microorganisms, inactivating them. It has been established that this technology is
capable of neutralizing E. coli bacteria by 99% and Salmonella bacteria by 99.9%. A design diagram,
key process parameters, and energy consumption models for a device for treating wastewater using
a pulsed electric field are also developed. Calculations have shown that a generator with a power
of 100–120 W is sufficient to neutralize 180 m³ of wastewater per day. Research results show that
pulsed electric field technology is an environmentally friendly, energy-efficient and promising method. To develop an effective electrotechnology for the disinfection of wastewater from various
harmful bacteria from industrial enterprises. Briefly describe the main methods or approaches used
in the study. Using a pulsed electric field, E. coli bacteria in wastewater are neutralized by 99% and
Salmonella bacteria by 99.9%. As a result of the studies conducted, it was found that the technology
for the disinfection of wastewater using a pulsed electric field is highly effective.
