A standard BOD test is run using seeded dilution water. The blank bottle containing the seeded dilution water has an initial DO of 9.2 mg/L and a final DO of 8.2 mg/L. The waste sample is mixed with seeded dilution water at a 1:25 ratio. It has an initial DO of 9.0 mg/L and a final DO of 2.0 mg/L. Calculate the BOD5.
A BOD test is run using 100mL of treated wastewater. The initial DO of the mixture after diluting the waste sample with distilled water is 9.0mg/L. After 5-day incubation, the DO measured was 4.0mg/L. After a long period of time, the DO is 2.0mg/L and no longer seems to be decreasing. Assume that nitrification has been inhibited.

A waste with a 5-day BOD (BOD)=200mg/L and k = 0.1 day¹ is discharged to a river at a rate of 1 m/s. The river has flow rate of 9 m/s and a background ultimate BOD (Lo) of 2 mg/L upstream of the discharge. (a) Calculate the ultimate BOD (Le) of the waste. (b) Furthermore, assuming instantaneous mixing after discharge, calculate Lo of the river water after it has received the waste. Ans.: (a) Ultimate BOD of wastewater = 508.3 mg/L, (b) Ultimate BOD of river water after discharge of waste-52.63 mg/L.
Jar testing was performed using alum on a raw drinking-water source that contained an initial turbidity of 20 NTU and an alkalinity of 35 mg/L as CaCO3. The optimum coagulant (alum: Al2(SO4)3•14H20) dosage was determined as 18 mg/L with a final turbidity of 0.25 NTU. Determine the quantity of alkalinity consumed as mg CaCO3 (1 significant figure)
