The key difference between aerobic and anaerobic sludge digestion processes is the presence or absence of oxygen in the process. Sludge digestion is a process used to stabilize sludge, reduce its volume, and decrease its odor and pathogen content, making it suitable for disposal or beneficial reuse.

The main end products of aerobic di....
