Untreated domestic sewage has a low:
Untreated domestic sewage has a low:
- A. BOD value
- B. \% of dissolved \( 0_{2} \)
- C. amount of dissolved salts
- D. value of suspended organic matter
Step-by-step solution
Untreated domestic sewage contains a high level of organic matter, which is decomposed by aerobic bacteria, leading to a high consumption of dissolved oxygen. As a result, the percentage of dissolved oxygen in untreated sewage is low.
