| Summary, etc. |
Achieving reliable water availability remains a significant challenge in developing<br/>nations like the Philippines, particularly in rural and informal settlements. Water<br/>treatment is an essential yet economically crucial process that has been the subject of<br/>extensive research. Pulsed Electric Field (PEF), is a non-thermal technology, has been<br/>proven effective in microbial inactivation through irreversible electroporation, making<br/>it a promising method for water disinfection. This study presents a hybrid-powered water<br/>purification system, integrating PEF and Ultraviolet-C technologies. A Marx generator<br/>is used that generates high-voltage pulses by stepping up a low DC input to significantly<br/>higher voltage levels. The generator operates by charging multiple capacitors in parallel<br/>and discharging them in series. The system is hybrid powered, in which it combines solar<br/>and AC power for both electronic and electrical components, respectively. Key<br/>objectives such as enhanced microbial inactivation, optimal energy efficiency, and<br/>compliance with potable water standards were successfully achieved. Numerous tests<br/>were conducted for the PEF only, UV-C only, and combined PEF and UVC samples,<br/>with and without 3-Stage Filtration. Results revealed that neither of the methods can<br/>stand alone in eliminating the bacteria and achieving the potable water standard.<br/>However, combining the PEF and UV-C with 3-stage filtration achieved significant<br/>microbial reductions for pathogens like Escherichia coli (E. coli) and Heterotrophic Plate<br/>Count (HPC). Physical and chemical parameters, including color, turbidity, total<br/>dissolved solids, and pH, were consistently within acceptable limits, ensuring safe water<br/>for consumption. The study’s findings underscore the synergistic effect of integrating<br/>PEF and UV-C technologies into a cost-efficient and scalable water purification solution,<br/>addressing water security issues. |
