What is a common outcome of anaerobic digestion in wastewater treatment?

• A. Increased waste volume
• B. Production of biogas
• C. Removal of chlorine
• D. Dehydration of sludge

Answer: (B)

Anaerobic digestion is a biological process that occurs in the absence of oxygen, primarily involving the breakdown of organic materials by microorganisms. One of the most significant outcomes of this process is the production of biogas, which mainly consists of methane, carbon dioxide, and other trace gases. Biogas can be harnessed as a renewable energy source, offering both environmental and economic benefits. During anaerobic digestion, the organic matter present in wastewater is effectively reduced, which in turn helps to manage waste while producing energy. This conversion of organic material into biogas is central to the efficiency of wastewater treatment and contributes to reducing greenhouse gas emissions. The other choices do not accurately describe a primary outcome of anaerobic digestion. For example, increased waste volume would contradict the purpose of anaerobic digestion, which is to reduce waste. The removal of chlorine and dehydration of sludge pertain to different processes in wastewater treatment, not specifically linked to anaerobic digestion.
