DNPAO
It stands for Division of Nutrition Physical activity and Obesity. It's main function is protection of the health of American people by promoting physical activity along with good food habits and nutritional foods. It follows global standards to enhance people's Health and keeps records so that states can have access whenever necessary.
Anammox
It stands for anaerobic ammonium oxidation.
It's an important process for biogeochemical nitrogen cycle which is there in many natural environments. This process cycles back the nitrogen to the atmosphere in the form of nitrogen gas. A reaction takes place in which nitrogen gas and water is produced by the combination of ammonium and nitrite ions.
EBPR
It is a phosphate removal process which is termed as Enhanced Biological Phosporous removal. This process is added as a modification to the conventional activated sludge removal process.
A2O
It is a Phosphorous and nitrogen removal process. It employs denitrification by following anoxic zone for nitrogen removal. Removal efficiency depends on the hydraulic retention time. Denitrifying phosphorous accumulating organisms also play an important and major role in this process and help in removal of nitrogen and phosphorus.
