Organic matter load on activated sludge refers to the amount of organic waste that is present in the sewage treatment plant. Synonyms for this term include organic loading, organic pollution, and organic content. Organic waste can come from a variety of sources including domestic sewage, agricultural runoff, and industrial waste. Treatment of organic waste is important to prevent environmental pollution and preserve public health. The activated sludge process is a popular method used in sewage treatment plants to remove organic waste from wastewater. This process relies on a mixture of bacteria to break down organic matter and convert it into harmless substances such as water and carbon dioxide.
