A wastewater sample is diluted in a standard BOD bottle by a factor of (1:30) with seeded dilution water to carry out the BOD test. Another (blank) bottle contains just seeded dilution water. Both bottles begin the test with DO of 9.2 mg/L. After 7 days the bottle containing waste has DO equal to 2.0 mg/L, while that containing just seeded dilution water has DO equal to 8.0 mg/L. Find the five day BOD of the waste assuming k=0.14 day-1 - 181 mg/l | 215 mg/L | 146 mg/L 215 mail 1 290 mg/L
