Is the PTA anaerobic wastewater removal rate low? What’s the reason?
Thread Content
Dear friends, our company uses a PTA anaerobic + two-stage aerobic process, but the anaerobic removal rate is very low. What’s the reason? (The temperature is maintained at around 38 degrees, the pH level is between 7.0 and 7.8; there are no toxic substances present. The alkalinity is currently between 1000 and 1500 mg/l, volatile acids are around 500-900, and total phosphorus ranges from 5 to 60.) Thank you all!
What is a water source? What are the COD values for the inlet and outlet water?
The COD of the anaerobic feedwater is generally around 5,000, and the sludge return flow rate is usually around 20 cubic meters!
5000 was fed in; what is the output now? What are the types and loads of anaerobic reactors?
What kind of anaerobic reactor is it? It seems that the acid-base ratio is a bit high
The removal rate in the EGSB anaerobic reactor can exceed 70%
Say more about the parameters. How long has debugging been going on? It’s likely that the debugging isn’t complete yet
What are the types and loads of anaerobic reactors?
