Common pollutants in reverse osmosis membrane components of reverse osmosis purified water equipment and their removal methods:

1. Calcium carbonate scale

When the scale inhibitor addition system fails or the acidification system appears, calcium carbonate may deposit. Therefore, the precipitation of calcium carbonate scale should be detected as soon as possible to prevent damage to the membrane surface caused by crystal growth. Attention: The pH value of the cleaning solution should not be less than 2.0.

Check the use of ammonia to improve the pH value, and sulfuric acid or hydrochloric acid to reduce the pH value.

2. Calcium sulfate scale

Cleaning solution is a good method to remove calcium sulfate scale on the surface of reverse osmosis membrane components in reverse osmosis pure water equipment.

3. Metal oxide scale

By using the above method to remove calcium carbonate scale, it is easy to remove deposited hydroxides (such as iron hydroxide).

4. Silica scale

For silica scale that does not coexist with metals or organic compounds, it can only be removed through water treatment cleaning methods. Please contact our company for specific methods.

5. Cleaning solution

When cleaning the reverse osmosis membrane components of the reverse osmosis pure water equipment, it is recommended to use cleaning solution for water treatment. It is important to analyze pollutants before cleaning. Detailed analysis and comparative analysis results. The cleaning methods and results obtained during each cleaning process should be recorded in order to find a better cleaning method under water supply conditions.
