• Nitrogen Content and Biochemical Oxygen Demand ( BOD )

  You can use this with the flow to find the mass of BOD passed in a day: You need to add 5 g of N for every 100 g of BOD, so you now use that ratio with the amount of BOD: This answers the initial question of how much elemental N is needed.

• Calculating amount of H3PO4 to reduce pH of wastewater
