One milligram per liter of ammonia-nitrogen is equivalent to 1.22 mg/L of ammonia., Confusion on this can result in reporting an ammonia violation when, in fact, there may not be a violation at all. The next article will deal with the other forms of nitrogen that we are concerned with in the wastewater field: nitrate, nitrite, and organic nitrogen. The information in this article is very general. As usual, check your …
