Enhancement of sludge electro-dewatering by anthracite powder
It took much less time (839 s–646 s) for the dry solids content to reach 43.5% when the sludge was conditioned, with an increase of 7.69%–17.4% removed filtrate mass at the same time ( Fig. 3 b). The results show that adding anthracite to sludge can increase dewatering rate and final dry solids content of sludge.
