The study was investigated the decolorization potentials of certan selected microbial species (bacterial) to an actual textile dyeing industry effluent. All the microbes tested namely (bacterial) Bacillus sp, pseudomonas sp, Acineto bacter, Legionella and Staphylococcus (bacterial) showed greater potential in decolorizing the dye effluent. Bacterial decolorization of textile effluents were crit...

In this research, the effects of different color intensities, anoxic + anaerobic times and types of substrate on color removal effectiveness were studied using 16-litre bench scale sequencing batch reactor (SBR) anoxic + anaerobic/aerobic models. The systems were fed with a synthetic wastewater containing 500 mg/l of COD, 50 mg/l of N, 15 mg/l of P along with 10, 40 and 80 mg/l of reactive diaz...

Laccases have been used for the decolorization and detoxification of synthetic dyes due to their ability to oxidize a wide variety of dyes with water as the sole byproduct. A putative laccase gene (LacTT) from Thermus thermophilus SG0.5JP17-16 was screened using the genome mining approach, and it was highly expressed in Pichia pastoris, yielding a high laccase activity of 6130 U/L in a 10-L fer...

Activated carbon is used in sugar industries for the removal of colorants from sugar liquor and for treatment of drinking water and industrial wastewater. Coal is a commercially used activated carbon, which is a limited non renewable resource. There are different renewable resources such as sugarcane Bagasse, Almond nutshells, Rice husk, Rice straw, Coconut shells, which could be used as altern...

Alginate-gelatin mixed gel was applied to immobilized laccase for decolorization of some synthetic dyes including crystal violet. The immobilization procedure was accomplished by adding alginate to a gelatin solution containing the enzyme and the subsequent dropwise addition of the mixture into a stirred CaCl(2) solution. The obtained data showed that both immobilized and free enzymes acted opt...

In the present study, the decolorization and degradation of Reactive Black 5 (RB5) azo dye was investigated by biological, photocatalytic (UV/TiO2) and combined processes. Application of Candida tropicalis JKS2 in treatment of the synthetic medium containing RB5 indicated complete decolorization of the dye with 200 mg/L in less than 24 h. Degradation of the aromatic rings, resulting from the de...

This study involves the photocatalytic degradation of Reactive Black 5 (RB5) and Reactive Orange 4 (RO4) dyes, employing heterogeneous photocatalytic process. Photocatalytic activity of different semiconductors such as titanium dioxide (TiO2) and zinc oxide (ZnO) has been investigated. An attempt has been made to study the effect of process parameters through amount of catalyst, concentration o...

In the process of biodegradation azo dye, redox mediators (RMs) were found to significantly enhance removal efficiency. this work, biodegradable RMs deriving from lignin-based monomers prepared via peroxidation investigate whether similar chemicals present in lignin-rich streams biorefineries could be used for biological treatment dyes. The as-prepared characterized by fourier transform infrare...

Environmental contamination, which is growing around the world, is a serious problem can not to be neglected. Among all contaminations, water pollution is a major problem. Azo dyes are one of the largest groups of pollutants found in the drinking water, coming from, and the food and textile industries. TiO2/Fe3O4 and TiO2/Fe2O3 nanocomposites with various ratios were synthesized by an ultrasoni...

Decolorization of synthetic azo dye solution of Congo red dye, as an anionic dye was studied in a batch reactor using Advanced Oxidation Process (AOP). Congo red has been selected amongst azo dyes due to its high solubility in aquatic environment. AOP is effectively removing color in azo dye wastewater due to its strong oxidizing property by breaking down the functional group that impacting col...
