Filtration is a process used to separate solids from liquids or gases using a filter medium that allows only the fluid to pass through. This technique is widely employed in various industries, including water treatment, pharmaceuticals, and food production, to ensure the purity and quality of products. The effectiveness of filtration depends on the size of the particles being removed and the type of filter used. There are several methods of filtration, such as gravity filtration, vacuum filtration, and membrane filtration. Each method has its own advantages and is chosen based on the specific requirements of the application. Filtration plays a crucial role in maintaining health and safety standards in many sectors.
