A BOD test was conducted on the unchlorinated effluent of a municipal treatment plant. The wastewater portion added to a 300-ml BOD bottle was 30 ml. and Ihe dissolved oxygen values listed below were measured using a dissolved-oxygen probe. Plot a BOD-versus-iime curve and determine the tivc-day BOD value.
Time (days) | DO (mg/l) | Time (day) | DO (mg/l) |
0 | 8.7 | 6.0 | 4.9 |
2.0 | 6.7 | 10.0 | 3.9 |
4.0 | 5.7 | 14.0 | 0.7 |
