Thank you both of you. Randy ,even if I manage to confuse you with litres, flow currently is 150lt/h ,in 650lt net volume[emoji6] ,you are absolutely right, it is now very clearly to me, that there's no way to measure with the current setup, different values of No3 or Kh at the reactor outlet.
And Ontheway thanks for the idea , to obtain evidence of denitrification , but 12h aren't to much time, for the water to be stagnant in the reactor? I red that you achieve the best results in this way, but again I am worried for such a long time to stop the flow in the reactor....
What do you both thing, of putting the filter supplying water to the reactor, on timer, and run it , e.g. for 10min per hour? In this way won't I boost the population of denitrification bacteria in the reactor?
