The impeller of the exhaust fan in the AB tank for my home’s biochemical water treatment system has been corroded; let’s discuss what could be the cause. There is a picture below.

The fan impeller has been corroded to such an extent! ! !
It’s likely a management issue – there is no proper attention paid to the physical and chemical properties of the materials, no consideration given to whether the equipment used in the production process is suitable, no attention paid to any abnormalities that may occur during production, and regular maintenance of the equipment is neglected. It’s purely a management issue.
I wonder what kind of corrosion this impeller has; management issues were not discussed.
It’s normal; not to mention the fan impellers, all the carbon steel in the entire biochemical tank will get corroded. Chloride ions, acidic and alkaline gases may be the culprits.

If you don’t know about your own materials, it’s difficult to make an assessment based solely on these photos; the issue related to \"AB tank exhaust gases\" should be addressed by those in charge of process analysis. Sulfur dioxide plus some water leads to this result, I guess. It’s just a speculation. Oh, right, you also didn’t specify whether it’s management or technical work – my involvement can’t be wrong, right? The state of this equipment means that my answer is the best one: it’s a management issue.
The management issue is correct. But the purpose of my post is to confirm whether it was caused by hydrogen sulfide corrosion, because I have never seen it before
If it is not uniform corrosion, liquid in the exhaust gas should be noticeable
For corrosion problems caused by harsh chemical environments, as shown in the image, if the impeller is not replaced during maintenance, Annekang Polymer Technology Company can be approached for repair using polymer materials after surface treatment; this approach saves time and effort and reduces inventory pressure.
Biological treatment tanks produce some methane and waste gases (such as hydrogen sulfide), which can cause corrosion; it is recommended to use a coating on the surface of the wind turbines for protection... As for those who claim that it’s due to poor management... there’s no need to make things out to be that serious. Many problems only become apparent once they occur; no one is perfect.
