Aerobic digestion of sludge is a process by which organic matter is broken down by aerobic organisms, such as bacteria, fungi, and protozoa. This process is characterized by the presence of oxygen, which is essential for the growth of the
organisms that are responsible for the breakdown of organic matter. The process of aerobic digestion is often used to treat
wastewater sludge, and the by-products of this process can be used as a fertilizer or soil amendment. During the process,
the organic matter is broken down into simple compounds, such as carbon dioxide, water, and minerals, which can be used by
plants.
