Reverse osmosis is the finest level of filtration available. The reverse osmosis membrane acts as a barrier to all dissolved salts and inorganic molecules, as well as organic molecules with a molecular weight greater than approximately 100. Water molecules, on the other hand, pass freely through the membrane creating a purified product stream. Rejection of dissolved salts is typically 95% to greater than 99%.
Classification of brackish water:
• Low salinity brackish waters: up to 5.000 ppm
• High salinity brackish waters: between 5.000 - 15.000 ppm
• Sea water: up to 45.000 ppm
Reverse osmosis is a technology that is used in the production of ultrapure water for use in the semiconductor industry, power industry (boiler feed water), and medical/laboratory applications.
