Recent insights on electrostatic filtration and its potential applications in food industry

Background: Oil contamination is always hazardous for the environment. Contamination in hydraulic and lubricating system oils is unavoidable, resulting in tribological issues. To minimize such problems, a variety of oil cleansers have been developed, which have substantially improved the system's reliability. Scope and approach: This review gathers the recent information regarding the electrostatic oil cleaners, their principle of filtration. Electrostatic oil cleansers remove polymerized oil oxidation products as well as micronsized particle pollutants. Electrostatic observance is a resourceful tool for detecting and tracking flaws and degradation of components, which is mandatory for system health management. Tiny particles are electrostatically driven to capture positive or negative charge particles on electrodes whereas large particles get trapped in the filter. Key findings and conclusions: Electrostatic filtration can be used to remove impurities from a liquid or solid food sample, usually by passing the sample through a filter made of charged particles. The charged particles attract the impurities, which are then removed from the sample. Electrostatic filtration can also be used to remove particulates, bacteria, viruses, and other contaminants. This method is often used in the food industry, as it is fast, efficient, and cost-effective. Electrostatic filters do not only show their best in the field of oil filtration but also in many other industries where their application is like in food industries for fine filtration in beverages as well as in the production field also. Thus, making these filters more applicable in the field of new industries and novel food processing techniques. The goal of this study is to raise awareness of both the technology's potential benefits and its existing research constraints to inspire greater research into this promising technology.
