Filtration is a process of separating solid particles or impurities from a fluid, typically a liquid or a gas, by passing it through a porous medium or a filter. The filter traps and retains particles while allowing the clean fluid to pass through. Filtration is commonly used in various applications, including water purification, air purification, oil refining, and many industrial processes. It is an essential method for removing contaminants, improving the quality of fluids, and ensuring the safety and efficiency of systems and processes. Different types of filters, Such as mechanical, biological, and chemical filters, are employed based on the specific requirements of the application.
