Abstract :

The untreated industrial wastewaterdischarged into the environment causes thecontamination of soil, water and air. Advanced treatment methods for enhanced wastewater treatment are attracting substantial interest among the currently employed unit processes in wastewater treatment. The textile industry is one of the predominant in wastewater production at current industrialized situation. The refused dyes at textile industry need to be treated in proper manner before its discharge in to water bodies. In the present investigation, hybrid treatment process has been developed for the treatment of synthetic mixed dye wastewater. Photo catalysis and ceramic nano porous membrane is mainly used for process integration to minimize the fouling and increase the flux. Commercial semiconducting powders (TiO2 and ZnO) has used as a nano photo catalyst for the degradation of mixed dye in the hybrid system. Commercial ceramic nano porous tubular membranes have been used for the rejection of dye and suspended catalysts. Photo catalysis with catalyst has shown the average of 34% of decolorization (RB-32%, BG-34% and CR-36%), whereas ceramic nano filtration has shown the 56% (RB-54%, BG-56% and CR-58%) of decolorization. Integration of photo catalysis and ceramic nano filtration has shown 96% (RB-94%, BG-96% and CR-98%) of dye decolorization over 90 min of operation.
