Low intensity ultrasound stimulates biological activity of aerobic activated sludge

LIU Hong, YAN Yixin, WANG Wenyan, YU Yongyong

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 1,   Pages 67-72 doi: 10.1007/s11783-007-0013-5

Abstract: 0.3 W/cm and an irradiation period of 10 min; more than 15% increase was achieved immediately after sonicationMore significantly, the AS activity stimulated by ultrasound could last 24 h after sonication, and theAS activity achieved its peak value within 8 h after sonication, or nearly 100% higher than the initiallevel after sonication.

Enhancement of sludge gravitational thickening with weak ultrasound

Panyue ZHANG, Tian WAN, Guangming ZHANG

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 5,   Pages 753-760 doi: 10.1007/s11783-011-0368-5

Abstract: This paper investigated the potential benefits of sonication on enhancing the sludge gravitational thickeningResults showed that weak sonication significantly changed the sludge settlability and the main mechanismThe changes in sludge behaviors by sonication were strongly influenced by power density and sonicationWeak sonication could substitute expensive polyelectrolyte coagulant for sludge thickening.Combination of weak sonication and polyelectrolyte could further reduce the settling time to 6 h.
