There are several key types of biological treatment, including:
Aerobic Treatment: Utilizes oxygen to degrade organic pollutants. Common methods include activated sludge and biofilm reactors. Anaerobic Treatment: Operates in the absence of oxygen, often used for high-strength wastewater. Anaerobic digesters are a common example. Composting: Decomposes organic waste into compost using microbial activity under aerobic conditions. Bioremediation: Uses microorganisms to clean up contaminated soils and groundwater.
