A » Scaling in RO membranes is primarily caused by the precipitation of sparingly soluble salts, such as calcium carbonate and calcium sulfate, from the feed water. These salts accumulate on the membrane surface, hindering water flow and reducing system efficiency. Contributing factors include high concentrations of scale-forming minerals, increased water temperature, and inadequate pre-treatment. Regular maintenance and chemical dosing can help mitigate scaling issues and prolong membrane lifespan.

A »Scaling in RO membranes is caused by the precipitation of sparingly soluble salts, such as calcium carbonate, calcium sulfate, and silica, when their concentration exceeds their solubility limits. This occurs due to the concentration of these salts as water passes through the membrane, leading to a reduction in membrane performance and lifespan.
