Ammonia nitrogen removal in lagoon systems.


Description

Biological treatment processes have been widely used for enhancing the removal of dissolved organic matter and nitrogen compounds from wastewater. In the United States wastewater treatment lagoons are the most common method of treatment for animal operations and rural domestic sewage. However, ammonia nitrogen is not effectively removed from the wastewater stream in these lagoons because of a lack of oxygen and a lack of surface area to encourage the growth of nitrifying bacteria.
