Aerobic Biological Treatment
Aerobic treatment of wastewater is a biological process that uses oxygen to break down organic contaminants and other pollutants like nitrogen and phosphorous. Oxygen is continuously mixed into the wastewater or sewage by a mechanical aeration device, such as an air blower or compressor. Aerobic microorganisms then feed on the wastewater’s organic matter, converting it into carbon dioxide and biomass which can be removed.
Aerobic treatment is usually used to polish industrial wastewater pre-treated by anaerobic processes. This ensures the wastewater is fully degraded and can be safely discharged in accordance with strict environmental regulations. Aerobic treatment processes are suitable for a range of industries such as food & beverage, chemical and municipal.
