Nanofiltration Membranes Market: Key Developments and Future Outlook
The nanofiltration membranes market is witnessing significant growth due to the rising demand for water purification, wastewater treatment, and industrial filtration solutions. Nanofiltration (NF) membranes are capable of removing contaminants, including organic compounds, divalent ions, and larger particles, making them highly effective for a wide array of applications. These membranes are positioned between reverse osmosis (RO) and ultrafiltration (UF) in terms of pore size and filtration capability. Their widespread application in a variety of industries, including water treatment, food processing, and pharmaceuticals, is a result of their capacity to remove contaminants selectively while preserving a high water flow.
The global nanofiltration membranes market size was valued at USD 1.33 billion in 2024 and is projected to reach from USD 1.46 billion in 2025 to USD 3.08 billion by 2033, growing at a CAGR of 9.8% during the forecast period (2025-2033).
