Textile industry uses large quantities of water for their process like scouring, desizing, dyeing, etc.
They generate wastewater in proportionate order. The dyes used in textile processes are a major
source of environmental pollution. Hence, there is a need to eliminate the dyes in the wastewater
before its discharge into the water bodies. Electrochemical oxidation method was adopted to
decolourize textile dye sample collected from textile industry. In this study using Graphite as an
anode and cathode, a number of batch experiments was run in a laboratory-scale to decolourize
the wastewater. The results are reported in terms of percentage removal of Chemical Oxygen
Demand (COD), Colour by varying NaCl concentrations and different current densities of 56, 96,
136, 176 and 216 A/m2. It was observed that increasing the NaCl concentrations and increased
current density brings down the colour and COD.COD and percentage colour removal were
70% and 89% respectively. Electrochemical oxidation method is an advanced technology which
is able to treat textile wastewater having high COD and colour efficiently before it is treated
further or discharged into the water bodies.
