Which Digestion Method Works Best for Different Industry Wastewaters?

The choice between aerobic and anaerobic digestion depends on the industry’s wastewater type. For medical wastewater, aerobic digestion is safer—it thoroughly removes pathogens and organic pollutants, ensuring compliance with strict discharge standards.
 
Municipal sewage treatment splits by scale: small-to-medium plants use aerobic systems for reliable effluent, while large plants add anaerobic digestion to sludge treatment for energy recovery and sludge reduction.
 
Food & beverage facilities, with high-organic-load wastewater, often combine both: anaerobic digestion first breaks down organics to produce biogas, then aerobic treatment polishes the effluent to meet standards. Chemical & pharmaceutical industries use anaerobic pretreatment to lower pollution loads before aerobic refining, depending on wastewater degradability.
