Effect of Free Nitrous Acid on Nitrous Oxide Production and Denitrifying Phosphorus Removal by Polyphosphorus-Accumulating Organisms in Wastewater Treatment

Figure 4

Various N₂O reduction rates in the presence or absence of nitrite (pH of 7.5, 8.0, and 8.5 corresponds to 0.0031, 0.00096, and 0.00035 mgHNO₂-N/L).
