Removal of color from textile wastewater by foamfractionation

The feasibility of foam fractionation for color removal from wastewater was assessed using actual textile wastewater as the research system and cetyl trimethyl ammonium bromide (CTAB) as the collector. The influences of surfactant concentration, initial color and pH on the removal efficiency were studied. The results showed that using CTAB as a collector for foam fractionation can provide good foaming quality and effectively remove color from textile wastewater. Also the results showed that by increasing the CTAB concentration, pH value and reducing of initial color, the dye removal efficiency of wastewater were increased. The optimum condition for dye removal efficiency from textile wastewater was achieved at CTAB concentration, initial color and pH value of 80 mg/L, 390 Pt-Co and 11 respectively. In this condition the removal efficiency was showed to be 99 percent
