From: Linkage of pipeline blockage to coagulation-flocculation process: effect of anionic polymer and pH
Effect of high Cu and pH on residual turbidity and soluble Cu at low initial turbidity (a, b) and high initial turbidity (c, d). (Experimental conditions: PACl dosage 0, 10, 20, 30, 40, 50, 100, 150, 200, and 225 mg L−1; polymer dosage 1 mg L−1; adjusted pH at 8, 8.5, 9, and 9.5; CuSO4 addition of 50 mg L.−1)
