Filtration is a process used to separate solids from liquids or gases by passing the mixture through a porous substance or medium that only allows the fluid to pass through while trapping the solid particles. Filtration is commonly used in various industries such as water treatment, pharmaceuticals, food and beverage production, and air purification. There are different types of filtration methods, including gravity filtration, vacuum filtration, and pressure filtration, each tailored to specific applications and efficiency requirements. Filtration is an essential process for removing impurities and contaminants from fluids and plays a crucial role in maintaining the quality and purity of various products and processes.
