Sludge treatment is focused on reducing sludge weight and volume to reduce disposal costs, and reducing potential health risks of disposal options. Water removal is the primary means of weight and volume reduction. The choice of a sludge treatment method depends on the volume of sludge generated, and comparison of treatment costs required for available disposal options. The sludge treatment is necessary to reduce and to ameliorate the sludge, which is produced within the biological wastewater treatment.
