The other was the release of ,acidity, and consumption of alkalinity by the nitrogen recovery. This acidification of the ,wastewater, can completely halt the N recovery process. Therefore, an abundant inorganic carbon supply in balance with the ,ammonia, in ,wastewater, is needed for a successful operation of the technology.

At 1.3 m•s–1, NH3 removal efficiencies ranged between 49.0% (pH8) and 84.3% (pH2). This ,study, has shown that slightly acidic scrubbing solutions are a practical means of removing ,ammonia, from air especially if the scrubber is designed to increase collisions between …

Alkalinity - Wikipedia
Alkalinity - Wikipedia

Alkalinity, (from Arabic "al-qalī") is the capacity of water to resist acidification. It should not be confused with basicity which is an absolute measurement on the pH scale.. Alkanity is the strength of a buffer solution composed of weak acids and their conjugate bases.It is measured by titrating the solution with an acid such as HCl until its pH changes abruptly, or it reaches a known ...

The pH of water indicates ,acidity, and alkalinity, which depends on the concentration of hydrogen and hydroxyl ions (Deshwal et al. 2016). The reason for ,acidity, is the presence of carbon dioxide which dissolves in water to form carbonic acid, thus increasing the ,acidity, of water ( Bialkowski 2006 ).
