Which of the following sewage handling technologies would be associated with maintaining a culture of aerobic bacteria?

Correct Answer: Option A — Biological sewage plant

Biological sewage treatment plants utilize aerobic bacteria to digest organic waste. These systems require a controlled environment where oxygen is supplied to maintain a healthy bacterial culture, which breaks down sewage into harmless byproducts before discharge, meeting international standards for marine sanitation devices as outlined in 33 CFR Part 159.
