Quizplus · Accepted Answer

Sedimentation of sludge occurs in primary sewage treatment, where wastewater is separated from the solid materials to prevent clogging of downstream pipes and to facilitate further treatment. Secondary sewage treatment involves biological processes to further reduce the organic matter present in wastewater, while tertiary treatment is focused on removing specific contaminants such as nutrients and pathogens. Water treatment involves the removal of contaminants from drinking water sources, and anaerobic sludge digestion is a process for treating the organic matter in sewage sludge.
