Global ion exchange membrane market growth is driven by growing demand for desalination from countries facing fresh water scarcity. The market is expected to witness significant growth over the forecast period, owing to rising focus on reducing dependence on conventional water treatment solutions and increasing adoption of energy-efficient ion exchange membrane technologies for desalination across Middle Eastern and Asian countries. Growth in end-use industries such as chemical processing and power generation can also drive the market growth.  

Growing demand from water treatment industry

Global ion exchange membrane market is expected to witness significant growth due to increasing demand from the water treatment industry. Proper treatment of water is essential before it is supplied for various industrial and municipal purposes. Ion exchange membrane technology is widely being used in desalination plants, wastewater recycling units and purifying brackish water. As the global fresh water reserves are under strain due to rising population and industrialization, more countries are turning to advanced water treatment technologies like reverse osmosis plants which employ ion exchange membranes. Their natural advantages such as high selectivity, energy efficiency and ease of operation as compared to other membranes boosts their usage.  The municipal sector has also ramped up spending on water treatment infrastructure to provide clean drinking water. Stringent regulatory mandates regarding wastewater discharge standards have propelled the need for advanced effluent treatment systems using ion exchange membranes. Their exclusion of undesirable ions while permitting passage of selective ions makes them suitable for a variety of industrial water purification needs. With growing fresh water scarcity becoming a worldwide concern, major investment is expected in large desalination projects as well as small decentralized community-level water treatment facilities which will boost demand for ion exchange membranes. Their important role in ensuring access to safe and clean water for all will boost research into developing more efficient and longer lasting membrane materials.
