Evaluation of Membrane Filtration and Ozonation Processes for Treatment of Reactive-Dye Wastewater
Abstract
Membrane filtration coupled with ozonation of the retentate was used for the treatment of colored textile wastewater. The textile wastewater examined was simulated from a commercial batch formula and contained organic dyes, sodium chloride, and copper among its components. A selected membrane filtration process generated a permeate with over 99 of the color and copper removed, while 85 of salt by mass and 85 of the original water were reusable. The effect of pressure, cross-flow velocity, feed concentration, and membrane fouling on permeate flux also was investigated. Subsequent ozonation of several different concentrated retentates each followed first-order reaction kinetics and removed color effectively. However, the decolorization rate constant decreased with increasing initial dye color. An empirical correlation was established for the apparent first-order rate constant of ozonation and the initial dye concentration. The relationship between the apparent rate constant and the dosage of ozone input also was investigated.

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.
