Filtration technologies are methods used to separate solids from liquids or gases by using a filter medium that allows only certain substances to pass through. Common types of filtration include mechanical filtration, where physical barriers trap particles, and membrane filtration, which uses semi-permeable membranes to separate substances based on size or charge. These technologies are widely used in various industries, including water treatment, pharmaceuticals, and food processing. In addition to traditional methods, advanced filtration technologies like nanofiltration and ultrafiltration have emerged, offering higher efficiency and precision. These techniques are essential for ensuring the purity of products and protecting equipment from contaminants. Overall, filtration technologies play a crucial role in maintaining quality and safety across multiple sectors.
