By 2044, The Share Of Non Reverse Osmosis Methods (MSF, MED, ED And Nanofiltration) In Total Installed Desalination Capacity Will Have Increased By At Least 15 Percent Compared To 2027 Levels.

Non Reverse Osmosis Methods Will Gain Share Toward 2044

The desalination market is growing from roughly 20 billion dollars in 2024 to over 51 billion dollars by 2035. This expansion is not a load that a single technology can carry. Although reverse osmosis holds the majority of installed capacity today, energy costs, concentrate brine management and differing water quality profiles are bringing alternative methods back to the fore in certain regions. For this reason, the share of MSF, MED, ED and nanofiltration in total installed capacity is expected to rise by at least 15 percent relative to the 2027 level by 2044.

Several structural factors lie behind this increase. First, energy intensive but heat recovery based systems are gaining economic appeal in regions where waste heat is abundant. Second, processes resistant to high salinity are being preferred in uses other than drinking water. Third, hybrid designs that recover concentrate brine instead of disposing of it are spreading. These factors create a picture in which reverse osmosis keeps its market leadership but its share erodes gradually.

For verification, technology breakdown capacity data published for 2044 will be decisive. If the share of non reverse osmosis methods in total capacity in the Desalination Technologies Market and Water Desalination Market reports comes out at least 15 points higher than the 2027 value, the prediction is considered verified. This threshold aims to measure a genuine structural shift rather than small fluctuations.

The indicators to watch are as follows.

• MSF and MED capacity increasing beyond the Gulf and North Africa
• Nanofiltration gaining share in industrial water recovery
• Electrodialysis and hybrid systems gaining visibility in new installations
