Current status of seawater desalination:<\/strong><\/h2>\n\n\n\n

The global daily output of seawater desalination is about 35 million cubic meters, of which 80% is used for drinking water, solving the water supply problem of more than 100 million people, that is, 1\/50 of the world’s population relies on seawater desalination for drinking water. According to statistics from the International Desalination Association<\/a><\/strong>, there are about 18,000 seawater desalination plants in 150 countries and regions around the world, among which reverse osmosis (RO) is one of the main membrane technologies for removing dissolved salts and other impurities from ocean or groundwater sources.<\/p>\n\n\n\n

Key Stages of Seawater Desalination<\/strong><\/h2>\n\n\n\n

Modern seawater desalination plants primarily use reverse osmosis (RO)<\/strong><\/a> technology to convert seawater into freshwater. During this process, parameters such as pH, conductivity, turbidity, and dissolved oxygen (DO) need continuous monitoring. Stable readings are crucial for detecting scaling, corrosion, and membrane fouling\u2014all of which directly impact system performance and maintenance costs.Key parameters that must be monitored include:<\/p>\n\n\n\n
