Membrane technology refers to the use of semi-permeable barriers to separate substances based on their size, charge, or chemical affinity. These membranes allow certain molecules or ions to pass through while blocking others. The development and application of membrane technologies have revolutionized various fields, including water treatment, gas separation, biotechnology, and food processing.

The fundamental principle behind membrane separation is the difference in permeability between the membrane material and the components of a mixture. Various types of membranes exist, each with specific characteristics suited for different applications. These include microfiltration, ultrafiltration, nanofiltration, and reverse osmosis membranes, distinguished by their pore sizes. Other types, like ion-exchange membranes or electrodialysis membranes, utilize electrical properties for separation.

In water treatment, membranes are crucial for desalination, removing contaminants, and purifying wastewater. Gas separation membranes are employed in industries to isolate specific gases, such as oxygen from nitrogen or hydrogen from carbon monoxide. In the pharmaceutical and medical fields, membranes are used in dialysis, drug delivery systems, and sterile filtration. The food and beverage industry utilizes membranes for concentrating juices, clarifying beverages, and producing dairy products. Continuous research and development are leading to new membrane materials and improved separation efficiencies, expanding the scope of membrane technology's impact.
