The proposed research aims to develop a concept design of a high voltage electrostatic sanitizer for capturing and destroying coronavirus particulates that could be traveling in a medium such as air, water, and foods. In the first step, the project will focus on airborne COVID-19 viral particles, in an effort to prevent airborne transmission of the virus and reduce human exposure. The project scope will be extended to the possibility of killing microorganisms in ionized water using high voltage. A range of different food and bioprocessing industries could benefit from a high voltage water sanitizer, as it has been observed that when cell membrane of different liquid pollutants is exposed to a high voltage electric field, irreversible breakdown of the cell membrane occurs which ultimately leads to their destruction and liquid sanitization. The device, which is going to be designed conceptually through this research work, would be an electrostatic sanitizer that uses high voltage to ionize air or water molecules containing viral or other microorganism particles and trap them. The current practice for removing airborne particles, whether high-efficiency particulate air (HEPA) purifiers or air ionizers, is successful in removing particles of biological origin like bacteria whose diameter are equal to 0.3 µm or larger. However, the COVID-19 virus is approximately 0.125 µm in diameter, which means that even the most powerful air filters would struggle to remove it from the air. Thus, this project aims at pushing the electrostatic sanitization boundaries towards large size viruses such as COVID-19 by a novel electromagnetic field analysis and design of electrodes and sanitizing partial discharge chamber.

这项拟议的研究旨在开发一种高压静电消毒器的概念设计，用于捕获和销毁可能在空气、水和食物等介质中传播的冠状病毒颗粒。在第一步，该项目将专注于空气传播的新冠肺炎病毒颗粒，以努力防止病毒通过空气传播，减少人类接触。该项目的范围将扩大到使用高压杀灭离子水中微生物的可能性。一系列不同的食品和生物加工行业可以从高压水消毒器中受益，因为已经观察到，当不同液体污染物的细胞膜暴露在高压电场中时，细胞膜发生不可逆转的破裂，最终导致它们的破坏和液体消毒。 该装置将通过这项研究工作进行概念性设计，它将是一种静电消毒剂，它使用高压将含有病毒或其他微生物颗粒的空气或水分子电离并捕获它们。目前去除空气中颗粒物的做法，无论是高效的颗粒空气净化器或空气电离器，都成功地去除了直径等于或大于0.3微米的细菌等生物来源的颗粒物。然而，新冠肺炎病毒的直径约为0.125微米，这意味着即使是最强大的空气过滤器也很难将其从空气中去除。因此，本项目旨在通过一种新颖的电磁场分析和电极设计以及局部放电室的消毒，将静电消毒的边界推向新冠肺炎等大型病毒。
