Membrane Filtration Market Report 2026

The membrane filtration market size has grown strongly in recent years. It will grow from $19.24 billion in 2025 to $20.78 billion in 2026 at a compound annual growth rate (CAGR) of 8%. The growth in the historic period can be attributed to increasing adoption of polymeric and ceramic membranes, rising wastewater treatment capacity, growing use in healthcare facilities, increasing food & beverage processing filtration, rising industrial process filtration demand.

The membrane filtration market size is expected to see strong growth in the next few years. It will grow to $28.13 billion in 2030 at a compound annual growth rate (CAGR) of 7.9%. The growth in the forecast period can be attributed to increasing development of thin film composite membranes, rising adoption of tubular and plate & frame modules, growing demand for high-efficiency filtration systems, increasing expansion in emerging markets for water treatment, rising technological improvements in membrane longevity and performance. Major trends in the forecast period include growth in reverse osmosis membrane adoption, increasing deployment of ultrafiltration systems, rising use of microfiltration techniques in industrial processes, expansion of nanofiltration applications in food & beverage, integration of hollow fiber and spiral wound module designs.

The rising incidence of water pollution and waterborne diseases is expected to drive the growth of the membrane filtration market. Water pollution occurs when harmful substances, such as chemicals or microorganisms, are discharged into streams, rivers, lakes, or oceans, reducing the availability of clean, drinkable water. The increase in water pollution has led to a higher prevalence of waterborne diseases. Membrane filtration offers an effective solution by using microfiltration or ultrafiltration to remove contaminants and improve water quality. For example, in August 2025, the Environment Agency, a UK-based government department, reported that in 2024, the total number of pollution incidents from sewerage and water supply assets increased by 29% compared with 2023, a rise considered unacceptable. Consequently, the growing occurrence of water pollution and waterborne diseases is fueling the expansion of the membrane filtration market.

Major companies in the membrane filtration market are focusing on developing innovative filtration solutions to enhance water quality, remove hard-to-treat contaminants, and improve wastewater treatment efficiency. Advanced membrane technologies, including ultrafiltration, nanofiltration, microfiltration, reverse osmosis, forward osmosis, and ozone-based systems, are being increasingly adopted to tackle difficult impurities such as oil and grease, optimize flow rates, and enable more effective backwashing and separation. For example, in September 2023, PPG Industries, a US-based manufacturer of paints, coatings, and adhesives, launched a new line of high-performance ultrafiltration membranes and filter elements. These products are designed to optimize industrial water reuse and wastewater treatment by offering superior mechanical, thermal, and chemical stability compared with traditional membranes.

In January 2023, Ingersoll Rand acquired SPX Flow's air treatment business for $525 million, aiming to expand its product offering in the broader compressor ecosystem. SPX Flow, a membrane filtration technologies provider, contributes to the membrane filtration market.
