Abstract:
Textile industry is the second polluter of clean
water. The effluent from textile industries consists of a
mixture of various dyes. These dyestuffs are made of complex
aromatic structures which are highly recalcitrant. The dye
colour in the water bodies become a major aesthetic problem
along with other ecological problems. Many methods are
used for dye removal process which includes chemical
coagulation, flocculation, chemical oxidation, photochemical
degradation, membrane filtration and aerobic and
anaerobic biological degradation. These methods have
certain limitations, and nothing is successful in the complete
removal of dye from wastewater. The ultimate use of this
methodology is to make out a high efficient process with
complete automation. Metal nanoparticles are also being
employed for decolourization of the textile dyes and they
show promising results in comparison to other treatment
methods. Instrumentation setup plays a major role in
automating the process.
