Fig. 1: Induction time of antiscalants using the stirred beaker test.

From: Investigation of scaling inhibition and biofouling potential of different molecular weight fractions of a PAA antiscalant

Fig. 1

Induction time (based on 1 NTU turbidity increase20,21) with 0.5 mg TOC L−1 of commercial PAA and its low and high MW fractions, against 68 mM sulfate solution and 33 mM carbonate solution (T = 11 °C, SICaSO4 = 0.72, SICaCO3 = 2.06). Error bars indicate standard deviation from duplicate experimental sample measurements.
