What Is Anaerobic Wastewater Treatment and How Does It Work?
What Is Anaerobic Wastewater Treatment and How Does It Work?

Anaerobic, wastewater treatment, is a biological process where microorganisms degrade organic contaminants in the absence of oxygen. In a basic anaerobic treatment cycle, wastewater enters a bioreactor receptacle. The bioreactor contains a thick, semi-solid substance known as sludge, which is comprised of anaerobic bacteria and other microorganisms.
