What DO level do you keep in bardenpho 5 step for NO3 removal
Volitales dropped to 60%. Mlss is 8500. Usually ran volatiles at 72% and always had less than .30. Will wasting improve NO3 numbers? Each time I waste to bring up volatiles the NO3 goes to 11.0 . Had low DOs for so long but whenever I increase air NO3 goes up. How can I reduce NO3?
