BOD: Biochemical Oxygen DemandBOD5 is the total amount of oxygen consumed by microorganisms during the first five days of biodegradation
BOD5 = (DOi - Dof)/(P) this is the five-day BOD of a diluted sampleWhere DOi = the initial dissolved oxygen (DO) of the diluted wastewaterDOf = the final DO of the diluted wastewater, 5 days laterP = the dilution fraction = (volume of wastewater)/(volume of wastewater plus dilution water)A standard BOD bottle holds 300 mL, so P is just the volume of wastewater divided by 300 mL
5.53)A cubic meter of a gravel-and-sand aquifer has been contaminated with 20 L of tetrachloroethylene. If the amount of tetrachloroethylene dissolved in aquifer water is 20 percent of its aqueous solubility,a) How much tetrachloroethylene is dissolved?b) How much remains as undissolved DNAPL mass?c) If the aquifer has a gradient of 0.001, use porosity and hydraulic conductivity data for gravel-and-sand aquifers to estimate the average linear velocity of the groundwater.d) How long would it take to remove the tetrachloroethylene?
