Improving flocculation and dewatering performance

2019-10-1  The thickener underflow density increased (from 1586.8 to 1625.7 kg/m 3) and the overflow turbidity reduced (from 57.7 to 41.6 NTU) with increasing the slurry pH (from 8.1 to 11.2). Increasing the flocculant dosage (from 8 to 13 g/t solid) was associated with a rising in the thickener underflow density (from 1589.1 to 1628.8 kg/m 3 ) and a ...
