Performance Evaluation of Selected Coagulants for the Removal and Reuse of Textile Wastewater Containing C.I. Reactive Black 5
Source abstract
Abstract
This study was carried out to investigate the comparative effectiveness of ferrous sulfate (FeSO 4 ) and magnesium chloride (MgCl 2 ) in removing color from synthetic C.I. Reactive Black 5 dye wastewater. After chemical coagulation, treated wastewater was reused in the wash-off process. Using 400 ppm of MgCl 2 , a color removal efficacy of 97% was achieved at pH 12 for synthetic Reactive Black 5 dye wastewater. Coagulant FeSO 4 yielded 85% color removal efficiency under the same conditions. The fabric washed with coagulant-treated wastewater had a total color difference (Δ E cmc ) value of <1.0, which is commercially acceptable. The colorfastness of the fabrics washed with coagulant-treated wastewater was comparable to those washed off with fresh water.
