The nonwoven filter media market is expected to grow at a CAGR of 5.9% during 2026–2034, driven by rising demand for air quality management, expansion of HVAC and cleanroom filtration, and increasing industrial and municipal water treatment needs. Nonwoven filter media is widely used because it offers scalable manufacturing, consistent pore structures, and cost-effective performance across both air and liquid filtration.
The water treatment market includes equipment, chemicals, technologies and services used to improve the quality of drinking water, process water and wastewater. Major treatment methods include filtration, sedimentation, biological treatment, disinfection, membrane separation, reverse osmosis, ion exchange, desalination and sludge management. These solutions serve municipal utilities, households, commercial facilities and industries such as power generation, chemicals, food and beverages, pharmaceuticals, mining, oil and gas and semiconductors.
The global water and wastewater treatment market is expected to record steady growth through 2035. One current industry estimate projects the market to increase from approximately USD 392.90 billion in 2026 to USD 690.97 billion by 2035, representing a compound annual growth rate of 6.46%. Asia-Pacific held the largest regional share in 2025. Secondary treatment and biological wastewater treatment represented major segments, while advanced treatment technologies are expected to expand at a higher rate.
Population growth, urbanization and increasing demand for clean water are major market drivers. Expansion of cities creates additional requirements for drinking-water supply, sewer networks and wastewater-treatment plants. Ageing water infrastructure in developed economies is also supporting investment in pipeline replacement, leakage control and treatment-facility modernization.
Industrial development is increasing demand for process-water treatment and wastewater recycling. Manufacturers must control suspended solids, chemicals, microorganisms and other pollutants before water is reused or discharged. Strict environmental regulations are encouraging industries to install advanced treatment systems and reduce freshwater consumption. Water-intensive sectors are adopting closed-loop and zero-liquid-discharge systems to improve resource efficiency.
Water scarcity represents an important long-term growth factor. Desalination, rainwater harvesting, treated-wastewater reuse and decentralized purification systems are gaining attention in regions with limited freshwater availability. Membrane technologies, including ultrafiltration, nanofiltration and reverse osmosis, are expanding because they can remove a broad range of contaminants.
Digital water management is a major market trend. Sensors, smart meters, remote monitoring and artificial intelligence are being used to track water quality, detect leaks, manage chemical dosing and predict equipment maintenance. Energy-efficient pumps, advanced membranes and resource-recovery technologies are also helping treatment operators control costs.
Market growth may be restrained by high infrastructure costs, energy consumption and limited municipal budgets. Older treatment facilities can be difficult to upgrade without interrupting services. Disposal of concentrated brine and treatment sludge creates environmental challenges. Shortages of trained personnel and differences in water-quality regulations may also affect technology adoption.
