Which of the following is NOT a benefit of sludge digestion in wastewater treatment?

Explanation:
Sludge digestion is aimed at stabilizing organic matter, reducing sludge volume, and recovering energy. In anaerobic digestion, microorganisms break down the organic solids to produce biogas (mostly methane), which can be captured for energy. This process lowers the mass of sludge by converting organics to gases and stabilizes the remaining solids, reducing odors and pathogens and making handling and disposal safer. Increasing sludge generation is not a benefit of digestion; in fact, digestion works to reduce sludge volume and improve manageability.
