Membrane technologies separate fluid mixtures in many different applications. They can separate materials based on size or electrical nature, and are widely used in the food processing and chemical industries, and to a lesser extent in wastewater treatment. Among many applications are: concentrating products; sterilizing through removal of bacteria or viruses; removing constituents (e.g., fats, proteins, acids) from process streams; desalination; demineralization; purification; and clarification. This end use briefing provides a quick tutorial on membrane technology in industrial facilities.
