The precision filter turns red during use
Thread Content
I was wondering if any of the more experienced colleagues have encountered this situation: when using a precision filter, if operation is paused for a while and then resumed, the filter may turn red, but the issue resolves itself after a short time. What is the reason?
Please, the original poster, provide information on the substances being filtered, the conditions, and other relevant parameters, so that we can better analyze the reasons.
There are likely two reasons for the oxidation of iron ions: 1) high levels of iron ions in the water; 2) the use of iron-based materials for equipment and pipes that lack anti-corrosion coatings or whose coatings have worn off. After all, there’s a saying that goes, \"Running water does not rot, and rotating hinges do not get damaged.\"
