Sludge stabilization is primarily aimed at which of the following?

Sludge stabilization primarily aims at reducing pathogens and odors. This process involves treating the sludge to eliminate harmful microorganisms and minimize unpleasant smells, which are common byproducts of raw sludge. The stabilization methods, such as aerobic digestion, anaerobic digestion, and composting, transform the organic matter into a more stable form, significantly lowering the risk of pathogen transmission when the sludge is disposed of or reused. By addressing the concerns of both health hazards and odors, proper sludge stabilization is crucial for safe and environmentally sound disposal or land application of biosolids.

While improving water clarity, enhancing nutrient recovery, and increasing the energy content of wastewater are important aspects of wastewater treatment processes, they are not the primary focus of sludge stabilization.
