Market Overview and Growth Outlook
USD 270 billion is the projected value of the global water treatment technology market by 2028, compared with an estimated USD 176 billion in 2021. The water treatment technology market is expected to grow at a CAGR of 4.9% during 2022–2028. The forecast reflects increasing requirements for water purification, improved water supply, and treatment infrastructure.
Urban migration has increased pressure on water supplies as cities and towns accommodate larger populations. Rising demand for water consumption and industrial applications is reinforcing the need for treatment facilities. Water collected from rivers, lakes, and reservoirs requires treatment before distribution, making purification infrastructure an essential part of urban water management.
The water treatment technology market size outlook reflects the importance of water quality and resource availability in infrastructure planning. Governments are increasingly focused on providing clean, usable water amid freshwater shortages. This focus, combined with industrialization and growing municipal requirements, contributes to sustained demand for treatment equipment, chemicals, and membrane-based purification technologies.

Market Segmentation Analysis
By End User Type, the market is divided into Industrial, Municipal, and Others. These categories capture the different requirements for treated water across economic activities and public infrastructure. Industrialization increases the need for chemically treated water, while population growth and urban migration reinforce municipal requirements for drinking water and treatment systems.
By Chemicals Type, the market covers Activated Carbon, Antifoams and Defoamers, Biocides, Coagulants and Flocculants, Corrosion and Scale Inhibitors, and Others. Chemical treatment remains relevant because water purification must address various chemical, biological, natural, and physical hazards. Treatment requirements also include ensuring that water is non-corrosive after purification.
By Membrane System Type, the market comprises Electrodialysis, Gas Separation, Microfiltration, Reverse Osmosis, Ultrafiltration, and Others. Reverse Osmosis accounted for the largest membrane system market share in 2021. Its substantial use in China and India underpinned its leading position, demonstrating the importance of membrane-based technologies within the broader water treatment industry.
