Abstract
In this project the polyelectrolyte-flocculated biosolids were pretreated by
ultrasonication in low power level to enhance the digestion performance. Compared
with the previous studies, the ultrasound applied here could not completely disrupt the
floc particles. While monitoring the time evolution of methane production and floc
properties, it is shown that cationic polyelectrolyte flocculation enhanced the methane
production in the initial stage of biosolids digestion but inhibited in contrary in the
later stage. After treated by low-power ultrasonication (0.33 Watt/ml) for 20 minutes,
the methane production of biosolids largely increased and reduced the negative effects
brought by cationic polyelectrolyte flocculant.
