Aerobic biological treatments use oxygen to break down organic pollutants in wastewater or waste materials through the action of microorganisms. These processes are commonly used in wastewater treatment plants to remove organic matter and nutrients.Microorganisms consume organic matter in the presence of oxygen, converting it into carbon dioxide, water, and biomass.Primarily used for municipal and industrial wastewater treatment, and in processes like activated sludge and trickling filters. Advantages include: Fast processing time, High efficiency in removing organic matter and nutrients (like nitrogen and phosphorus) and Produces less odorous by-products compared to anaerobic treatment.
