Calculation of deaerator
Thread Content
I would like to ask the experts here: how is the value of dissolved oxygen at the outlet, in mg/L, calculated for the design of rotary film deaerators? I have a deaerator for which the required value is an dissolved oxygen level of ≤0.007 mg/L under normal operating conditions. I’m not sure exactly how this value is determined; I hope the experts can provide some guidance. Thank you!

Our company has built two such units; we don’t know how to carry out the calculations, as there’s no ready-made method for such calculations. We had to find suppliers who specialize in deaeration heads, and we also need to provide the storage tanks underneath. Such suppliers can be found in Shandong and Dalian. These units were developed through experiments, and the details aren’t made public
Oh, okay, I’ll look for more information. Thank you.
