How to determine where the reverse osmosis equipment failure(2)

Sep 29, 2017

The first to check the instrument to see if the operation is correct.

Second, the operation of the data to be confirmed again to see if it is missing or improper operation.

The third is to determine whether the mechanical problems, or chemical problems caused by the failure.

The fourth is to analyze the failure of chemical reactions due to chemical reactions caused by the failure.

The fifth pair of pollutants to identify, find the reasons.

Use the reverse osmosis equipment should pay attention to the following questions

In any case, do not let the water with free chlorine come into contact with the composite membrane element. If this contact occurs, the performance of the membrane element will be degraded and the performance will not be restored. After the tubing or equipment is sterilized, There is no free chlorine in the feed water of the reverse osmosis membrane element. In the inability to determine whether there is free chlorine, it should be verified by laboratory tests. Sodium bisulfite solution should be used to neutralize residual chlorine and ensure sufficient contact time to ensure complete reaction.

During the warranty period of the reverse osmosis membrane element, it is recommended that each reverse osmosis membrane cleaning should be carried out after consultation with the company's on-site service personnel at least during the first cleaning. Cationic surfactants should be avoided in cleaning solutions because irreversible contamination of the membrane elements may occur if used. Cleaning the reverse osmosis equipment should pay attention to these problems.

 

The above is about the reverse osmosis equipment failure to judge.
