The commercial water treatment systems market in the United States is valued at over $4.5 billion, according to new research from Verify Markets.

The market research firm said that the commercial water treatment market is driven by a wide range of factors, including water quality issues, growing public awareness of health & safety, inadequate municipal infrastructure, regional regulations, economic recovery and the return of private sector confidence.

Within the overall commercial market, the hospitality and food service verticals represent the largest single share but growth is strongest in the healthcare sector.

Membrane technology is still ahead in the U.S. market but higher recovery reverse osmosis systems are gaining traction.
