  • A review on sludge dewatering indices Water

    Evaluation of sludge dewaterability is critically necessary for any sludge treatment system where optimizing the dewatering process is the aim. However, this work is relatively challenging due to the unpredictable and elusive behaviour of all sludge types, especially bio-sludge, as well as variations in solid–liquid separation methods.
