Color is the most obvious contaminant to be noticed in textile dye wastewater. A numbers of methods and materials have been used in textile dye effluent treatments. Generally, the chemical approaches are mostly utilized by employing coagulation and flocculation mechanisms. The efficiency of dye removal depends on the type of dye, pH, coagulant type and dosage. The amount of the unfixed dyes lost into effluent is variable with reactive dyes reported to be highest, ranging from 20-50%.
A comparative study was therefore conducted to optimize treatment of Reactive Super Black dye effluent from a textile factory using Alum, Polyferrous Sulphate (PFS) and Polyalluminium Ferric Chloride (PaFC) coagulants at varied pH and dosages. Treatment efficiency was assessed by analysis of total dissolved solids, conductivity, salinity, COD, colour concentrations, turbidity and quantities of slu.. View More»
