Filtration technology refers to the process of separating solids from liquids or gases using a filter medium that allows only certain substances to pass through. This technology is widely used in various industries, including water treatment, air purification, and food processing, to remove contaminants and improve the quality of the final product. Different types of filters, such as membrane filters, activated carbon, and HEPA filters, are designed for specific applications. Each type has unique properties that determine its effectiveness in capturing particles, bacteria, or pollutants, making filtration technology essential for maintaining health and safety standards in both industrial and residential settings.
