2.5. Scale inhibition experiments
Two scale-inhibitors, Preatreat Plus 0400 and Preatreat Plus Y2K
(King Lee Technologies, San Diego, CA), were used in this study.
Preatreat Plus 0400 was selected specifically to inhibit the formation
of calcium sulfate and calcium carbonate and Pretreat Plus Y2K
was selected to inhibit the formation of a broad spectrum of minerals
(e.g., silica, calcium carbonate, barium/strontium sulfate, iron,
aluminum, and calcium phosphate) [30]. Brine A was dosed with
scale inhibitor during specific VEDCMD and FO experiments. For
the VEDCMD experiments, Pretreat Plus 0400 doses ranged from
2 to 8 mg/L. For the FO experiments, the Pretreat Plus Y2K recommended
dose of 10 mg/L [5] was used.
