Soluble arsenic removal at water treatment plants
Abstract
Conventional treatment steps can be extremely effective at removing arsenic. Arsenic “profiles” were obtained from full‐scale conventional treatment (coagulation, Fe–Mn oxidation, or softening) plants, facilitating testing of theories regarding arsenic removal. Soluble As(V) removal efficiency was controlled primarily by pH during coagulation, by Fe+2 oxidation and Fe(OH)3 precipitation during Fe–Mn oxidation, and by Mg(OH)2 formation during softening. Insignificant soluble As(V) removal occurred during calcite precipitation at softening plants or during Mn+2 oxidation–precipitation at Fe–Mn oxidation plants. The extent of soluble As(V) removal during coagulation and softening treatments was lower than expected. Somewhat surprisingly, during coagulation As(V) removal efficiencies were limited by particulate aluminum formation and removal, because much of the added coagulant was not removed by 0.45‐μm‐pore‐size filters. At one utility, reducing the coagulation pH from 7.4 to 6.8 (at constant alum dose) improved removal of particulate aluminum, thereby enhancing soluble As(V) removal during treatment.

“Furthermore, the initial As concentration, pH, natural organic matter (NOM), and the presence of anions essentially affected the rate of adsorption of As(V)on TiO2 [150, 153–155].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
