“…Our study seems to confirm that polyelectrolyte addition does not always exert a positive effect during EDW [36]. The effect of polyelectrolyte is more pronounced for the stage where the dewatering relies on filtration, i.e.…”

“…Indeed, aerobically stabilised sludge can hardly exceed 25-30% (wt%) DS content, even when dewatered with filter presses which usually operate at higher pressure and produce drier sludge [33]. Moreover, the polyelectrolyte addition does not affect the dewaterability under the EDW and it suggests that the chemical input can be reduced [36].…”

“…Citeau et al (2011) also studied the influence of polyelectrolyte type and dosing on EDW efficiency. However, so far the high variability of sludge samples produced by different WWTPs (in terms of DS, VS/DS, conductivity) prevented from building a general model capable of predicting EDW efficiency for all the sludge types.…”

“…However, the high DS values demanded for thermal valorisation of sludge cannot be achieved by mechanical dewatering techniques. , and Tuan et al [10] reported that the pH drop relates to the reduction of the absolute value of the zeta potential, thus the decrease in pH (specifically at the anode) reduced the electro-osmotic flow during direct current application [1, 5,8,11].…”

Anodes such as stainless steel will be subject to…”
