Water Desalination Equipment Market to Reach $32.3B by 2035, Growing at 8.6% CAGR | Transparency Market Research

Water desalination equipment, including RO, MSF and ED technologies, play a vital role in addressing water scarcity by converting saline water into freshwater.

WILMINGTON, DE, UNITED STATES, September 11, 2025 /EINPresswire.com/ -- The global water desalination equipment market is poised for significant growth in the coming years. Valued at USD 13.0 billion in 2024, the market is projected to expand at a Compound Annual Growth Rate (CAGR) of 8.6%, reaching an estimated USD 32.3 billion by the end of 2035. This growth is primarily driven by the increasing global water scarcity, technological advancements, and a growing demand for reliable and sustainable freshwater sources.

Market Overview: Water desalination equipment refers to the systems that convert saline or brackish water into potable freshwater, addressing the critical issue of water scarcity in arid and semi-arid regions. Desalination plays an essential role in supplementing freshwater supplies for municipal, industrial, and agricultural needs, particularly in regions with limited access to natural freshwater sources. Reverse Osmosis (RO) is the dominant technology in the market due to its energy efficiency and scalability, making it the preferred choice for large-scale desalination plants worldwide.
The market is segmented by technology, source of water, and application. The technologies used in desalination equipment range from Reverse Osmosis (RO) to Multi-Stage Flash (MSF) and Multi-Effect Distillation (MED). The primary sources of water for desalination are seawater, brackish water, and river water. The applications for desalinated water span municipal, industrial, and agricultural uses, with each sector benefiting from advances in desalination technology.

Key Drivers of Market Growth

Several factors are driving the demand for water desalination equipment, which include:
1. Escalating Global Water Scarcity: The global water crisis is intensifying, with over 2.3 billion people living in water-scarce regions. By 2030, global water demand is expected to surpass supply by 40%, underscoring the need for alternative water sources like desalination.
2. Rising Demand for Freshwater: Population growth, urbanization, and industrialization have led to a significant increase in demand for clean freshwater. Desalination offers a viable solution, particularly in regions that lack access to natural freshwater bodies.
3. Technological Advancements: Innovations in desalination technology, including energy recovery devices, next-generation membranes, and hybrid systems, are making desalination processes more efficient, cost-effective, and environmentally friendly.
4. Expanding Industrial and Municipal Applications: Desalination is increasingly used in industries such as oil & gas, power generation, and municipal water supply. As industries expand, the need for sustainable water solutions grows, making desalination equipment indispensable.
