Assessment of Chitosan Conditioning in a Synthetic Anaerobic Digested Sludge System

摘要: Effects of dosage and pH in chitosan conditioning were investigated for studying the anaerobic digested sludge dewatering characteristics using a modified synthetic system. A comparison was made between different cations cationic polyelectrolytes. Capillary suction time, turbidity supernatant, filtered cake solids content measured to assess dewaterability. Floc sizes Fourier Transform Infrared spectrums also examined conditioned properties. Experimental results indicate that with showed remarkable dewaterability close resemblance real strong correlation floc size observed increasing dosage. The optimum found acidic region. comparable one trivalent cation. This proposed behaves typical when chitosan.
