Activated Carbon Aided Alum Coagulation For Removal Of Textile Dye From Dye Water
The processes of adsorption followed by coagulation was evaluated for the removal of three textile dyes (CIBACRON Yellow C5G, Remazol Blue RGB and Remazol Red RGB) from water in a laboratory-scale experiment. The adsorption efficiency of manufactured powdered activated carbon (Malbon R4) for t...

| Summary: | The processes of adsorption followed by coagulation was evaluated for the
removal of three textile dyes (CIBACRON Yellow C5G, Remazol Blue RGB and Remazol
Red RGB) from water in a laboratory-scale experiment. The adsorption efficiency of
manufactured powdered activated carbon (Malbon R4) for three dye solutions was also
investigated. Batch experiments showed that the adsorption of dyes increased with an
increase in dye concentration and carbon dose. The right sequence of operation was
identified for the combined treatment system. The results indicated that maximum
percentage of dye removal by adsorption on Malbon R4 for the dyes achieved was 52.15-
83.53 %. The maximum dye removal efficiencies for 20 mg/l and 50 mg/l of dye
concentration (for three dyes) with adsorption followed by coagulation were 96.16-99.78%
and 96.71-99.60 %, respectively. The combined adsorption-coagulation process has the
capability of near complete dye removal. More research should be done with different
types of activated carbons and coagulants for removal of dye from dye wastewater. |
