We have a anaerobic contact basin used for treating industrial wastewater. We currently have VFAs of 23 and a total alkalinity of 1500 (without NaOH being added). Should I be concerned that the total alkalinity is 1500 (which some think is too low) or should I focus more on the VFA/TA ratio, which is .01 right now? I believe that adding NaOH is not necessary as long as my ratio stays below .1. I am not worried about a sudden increase in influent VFAs due to a large EQ tank ahead of the anaerobic contact basin.
THANKS!!
