WebA pH of 7.0 to 7.2 is normally used to maintain reasonable nitrification rates, and for locations with low-alkalinity waters, alkalinity is added at the water resource recovery facility to maintain acceptable pH values. The amount of alkalinity added depends on the initial alkalinity concentration and amount of NH4-N to be oxidized. WebEstuaries intercept nitrogen as it travels from watersheds to coastal waters, but the effectiveness of this ecosystem service varies widely. PIE scientists discovered that the magnitude and timing of salinity changes in tidal waters may control the processing of the nitrogen, which may impact the frequency and severity of algal blooms along the coast.

WebDenitrification is the last step in the nitrogen cycle. It is a naturally occurring, microbially mediated process, where nitrate is used as a form of energy for denitrifiers. In this process, soil bacteria convert plant-available soil nitrate (NO 3–) into nitrogen (N) gases that are lost from the soil. Denitrification produces several gases ...
