Reverse osmosis water treatment equipment is highly effective for water purification. Many users may notice that scaling occurs over time. What are the causes of scaling in reverse osmosis systems? How can scaling be prevented?

During the reverse osmosis process, insoluble salts are left on the membrane surface, forming solid precipitates. Specifically, as the reverse osmosis equipment operates, the low-pressure flushing process generates fresh water, while the water concentration on both sides naturally increases. This increase leads to a higher salt concentration, containing a large amount of precipitable substances, which over time can cause scaling.

Therefore, as long as the solubility of salts does not exceed the saturation limit, the occurrence of scaling can be effectively prevented. In terms of design, to better replace the concentrated water, it is advisable to ensure a low salt content in the concentrated water.

Furthermore, trace inorganic substances in some natural water bodies, such as phosphate, iron, and aluminum, which have low solubility products and are prone to scaling, may be introduced into the water supply due to human factors like chemical addition. Therefore, when dosing chemicals into the system (e.g., flocculants, coagulants, scale inhibitors, acids, and bases), the influence of these artificially introduced ionic components should be taken into account.

Above is the explanation of scaling causes and preventive measures for reverse osmosis water equipment provided by our large-scale reverse osmosis water equipment manufacturer. We hope it is helpful to you.
