... and denitrification processes for ammonia and nitrogen removal. The favorable conditions for nitrifying bacteria were provided by using influent flow splitting and step feeding. The relative predominance of nitrifying bacteria resulted in an increase of nitrification rate and decrease of nitrification time...

...R. Hofmann; R.C. Andrews This note identifies potential side effects of using ammonia to inhibit bromate formation during the ozonation of drinking water, and makes preliminary predictions of their significance. Based on kinetic calculations, it is expected that ammonia would not exert...
