Liquid filtration is a process used to separate solid particles from liquids. This is typically achieved by passing the liquid through a filter medium, which allows the liquid to flow while trapping the solid particles. Common filter media include paper, cloth, or specialized materials like membranes. Liquid filtration is widely used in various industries, including water treatment, food and beverage production, and pharmaceuticals. The effectiveness of liquid filtration depends on factors such as the size of the particles, the type of filter used, and the flow rate of the liquid. Techniques can vary from simple methods, like using a coffee filter, to advanced systems like microfiltration and ultrafiltration. These methods help ensure the purity and quality of liquids in both industrial and household applications.
