a. To measure the BOD5 of a wastewater, threedilutions are prepared. The data for the tests are provided below.What is the BOD of the wastewater?
Wastewater (mL) | DO t = 0 | DO t = 5 days |
| 5 | 9.2 | 4.8 |
| 8 | 9.1 | 3.2 |
| 10 | 9.1 | 1.8 |
b. The BOD5 of a wastewater is estimated to be 75mg/L at standard temperature. The k value is 0.150 day-1at standard temperature. What is the ultimate BOD?
