By Technology Insights
Reverse Osmosis Systems Segment Captured Largest Share in 2025
The reverse osmosis systems segment captured largest share. Segment’s dominance is accelerated by its growing adoption as it helps in eliminating several aqueous salts and metal ions such as chromium, copper, lead, sodium, and chloride. Additionally, these water treatment systems are highly versatile and find numerous applications in both residential and commercial settings, which positively influences segment’s growth.
The distillation systems segment will grow at highest growth rate. This growth is attributed to growing use of distilled water in wide range of applications including cooking, drinking, bathing, cleaning, and laundry. Their effectiveness in eliminating various specific contaminants like volatile organic compounds and heavy metals, has also been creating substantial demand for these treatment systems.
By Application Insights
Industrial Segment Held the Majority Revenue Share in 2025
The industrial segment held the majority revenue share. This dominance is attributed to continuous expansion of various water-using industries such as chemicals, food & beverages, and textiles, as increasingly realizing the importance of treated water for their processes. Growing industrialization especially in developing nations that led to increased demand for clean water in several industrial processes, further contribute to the demand for reliable water treatment systems.
