Q: Did you ever observe a crud burst?
A: If not carefully controlled and without proper supervision, crud bursts that plug up other hollow conductors or the filters might occur. However, with our careful control of the process, we have never experienced such a crud burst.
Q: Would you rather recommend high oxygen or low oxygen water treatment?
A: All of the chemical regimes have their advantages and disadvantages. If you have stable conditions within the specifications in the CIGRE guidelines, do not change anything.
Q: What limitations does the process have?
A: We have two limitations: first, as with any type of chemical cleaning, we need a little flow through the cooling water channel, so that our chemicals can reach the copper oxides. Second, our method is very efficient on copper oxides, however, foreign material will not be removed.
