Claim:
1. A system, comprising: a media filter configured to facilitate conversion of nitrogen from a first form that is less likely to outgas from water to a second form that is more likely to outgas from the water; a dosing mechanism configured to dose a carbon feedstock into influent water of the media filter to promote the conversion; a first sensor configured to detect a level of carbon in effluent water from the media filter; a second sensor configured to detect a level of nitrogen in effluent water from the media filter; and a controller configured to control the dosing mechanism based upon the levels of carbon and nitrogen in effluent water from the media filter; wherein the controller is further configured to reduce a carbon feedstock dosing rate in response to an increasing level of carbon in effluent water from the media filter; and the first form is one or more of: nitrate or nitrite.
