This study introduces mill scale as a ballasted flocculant (BF). The behavior of activated sludge is studied after the addition of BF, with the objective to improve the aggregation of activated sludge particles and enhance its settleability. The efficiency of BF is evaluated by varying its dosage (mill scale to sludge weight ratio = 0.2–2 ...
