Chemical conditioning of aerobically digested sludge using polyelectrolytes with different charge densities

Applied Water Science
This research was carried out to evaluate the effects of different dosages (1.85–4.44 g kg−1 Ts−1) of three cationic polyelectrolytes with charge densities (CD) of 20%, 40%, and 60% on the dewatering properties of an aerobically digested sludge.

ELECTRO-OSMOTIC DEWATERING OF ANAEROBICALLY AND AEROBICALLY STABILISED SLUDGE [PDF]

, 2016
Dewaterability of sludge produced by Wastewater Treatment Plants (WWTPs) is often poor, reaching less than 25% dry solids (DS). Electro-dewatering could be a suitable technique to further reduce water content of the sludge by up to 20%.
