Where to Find a Nitrification Denitrification Activated Sludge Process Excel Spreadsheet
To obtain a nitrification denitrification activated sludge process Excel spreadsheet, click here to visit our spreadsheet store. Look in the wastewater treatment category on the Download page. This Excel spreadsheet is intended for completely mixed activated sludge nitrification/denitrification calculations. You can buy a convenient nitrification denitrification activated sludge process Excel spreadsheet for a very reasonable price. This spreadsheet calculates the completely mixed aeration tank volume for BOD removal and nitrification as well as the volume for a pre-anoxic tank to achieve denitrification.. It is available in either U.S. or S.I. units. Read on for information about using a nitrification denitrification activated sludge process Excel spreadsheet.
Background for Nitrification Denitrification Activated Sludge Process Excel Spreadsheet
The activated sludge wastewater treatment process can be designed for removal of BOD (organic matter that exerts an oxygen demand in the water), or for BOD removal and nitrification, or for BOD removal, nitrification and denitrification. Nitrification is oxidation of ammonia nitrogen in the wastewater to nitrate and denitrification is removal of nitrate from the wastewater.
A flow diagram for a nitrification denitrification activated sludge process is shown below. It includes a completely mixed activated sludge aeration tank for BOD removal and nitrification as well as an anoxic basin for denitrification.
