PB - Zielona Góra: Oficyna Wydawnicza Uniwersytetu Zielonogórskiego N2 - The aerobic stabilization of excess sewage sludge using low frequency ultrasound (25kHz) was investigated. The mechanically thickened excess sludge was obtained from full-scale wastewater treatment plants. The samples of sewage sludge were prepared by dissolving drinking water to obtain initial total solid concentration of 1800 mg/dm3. N2 - Five samples were treated with ultrasound of different power per sample volume: 3,12; 6,25; 12,5; 25,0 and 50,0 Wh/l. The experiments show that ultrasonic pre-treatment with 50 Wh/dm3 power increases the digestion of organic matter in aerobic stabilization of sewage sludge.
