Ammonia production - Wikipedia
Ammonia production - Wikipedia

Ammonia, is one of the most highly produced inorganic chemicals. There are numerous large-scale ,ammonia production, plants worldwide, producing a total of 144 million tonnes of ,nitrogen, (equivalent to 175 million tonnes of ,ammonia,) in 2016. China produced 31.9% of the worldwide production, followed by Russia with 8.7%, India with 7.5%, and the United States with 7.1%. 80% or more of the ,ammonia, ...

Anaerobic lagoon - Wikipedia

An ,anaerobic lagoon, or manure lagoon is a man-made outdoor earthen basin filled with animal waste that undergoes anaerobic respiration as part of a system designed to manage and treat refuse created by concentrated animal feeding operations (CAFOs). Anaerobic lagoons are created from a manure slurry, which is washed out from underneath the animal pens and then piped into the lagoon.

Ammonia, is a common liquid used in households and industry, easily identified by its distinctive smell. Many of ,ammonia,’s uses and benefits derive from its pH level, which is the measure of how acidic or alkaline (basic) a solution is. The standard pH of ,ammonia, explains many of the properties of the chemical. ,Ammonia, ...

Ammonia, (NH 3) is a common toxicant derived from wastes (see Figure 1), fertilizers and natural processes. ,Ammonia nitrogen, includes both the ionized form (ammonium, NH 4 +) and the unionized form (,ammonia,, NH 3). An increase in pH favors formation of the more toxic unionized form (NH 3), while a decrease favors the ionized (NH 4 +) form.
