I would like to ask about the use of citric acid for cleaning ferric oxide scale
Thread Content
I would like to ask whether there are any interfering factors during the use of citric acid to remove iron tetraoxide scale; such factors might prevent the effective removal of this scale or lead to the formation of other passivation layers that hinder the cleaning process. Additionally, I wonder if iron/copper citrate can also easily decompose into iron oxides, thereby causing scaling to occur again.
It is recommended to use ultrasonic physical scale prevention and removal systems that operate in real time online, and then your concerns will be resolved.
