Which of the following is a true statement about the sewage treatment process?

The sewage treatment process involves various methods to manage waste, where maceration plays a significant role. Macerators are devices used to grind solid waste into smaller particles, which helps in facilitating further treatment processes, including biological treatments where bacteria, both aerobic and anaerobic, degrade the waste.

Choosing the statement about maceration not being related to bacteria highlights the physical aspect of the process, which is primarily mechanical in nature. While bacteria are indeed crucial for the biological breakdown of sewage, maceration itself is a preparatory step that ensures solids are reduced in size for more effective treatment. This is why stating that maceration is not related to bacteria reflects an understanding of the distinct phases of sewage treatment.

Other options incorrectly link the roles of bacteria or misrepresent the functions of macerators in relation to different states of waste management, thereby isolating the specific mechanical function of maceration from biological treatment processes.
