Abstract Synthetic dyes, particularly reactive and acid dyes, are commonly used in the textile industry because of their advantages as excellent color fastness and brightness. Also, surfactants are used for an increment of coloring success in the textile industry. One of the major problems concerning textile wastewater is the treatment of the effluents containing both dyes and surfactants. Biological treatment systems are recommended as useful, economic and eco-friendly methods for treatment of industrial wastewater. The purpose of this study was to investigate the binary removal of a textile dye and a surfactant by growing Aspergillus versicolor culture in molasses medium. The effect of dye and surfactant concentration on the removal of dye and surfactant was determined. This study resulted that 100% of the surfactant and dye molecules removed together with the formation of a dye-surfactant complex by fungus. It is concluded that binary removal systems are very efficient for industrial wastewater treatment.

All over the world, the treatment of textile wastewater has become a significant problem due to the development of the textile industry. Particularly, the treatment of synthetic dyes, which are found abundantly amounts in textile wastewater, has gained importance. Recent studies have focused on the use of biological treatment technologies to remove pollutants in water. On the other hand, the disposal of wastes from biological treatment technologies was considered as another environmental problem. This study aims to compare the antimicrobial properties of the extract obtained from dye loaded and un-loaded lichen biomass after the biosorption process. According to the results of this study, it was found that the extract obtained from the waste lichen biomass, which has loaded with the textile dye in the decolorization process, showed a similar antimicrobial effect with the unloaded lichen extract. To sum up the waste lichen biomass used to remove textile dyes can be reused for the application of antimicrobial products.

Living Being

Life of living or non-living being depends on water; in short, water is life. But these days, with the growing industrialization, it is spoiling a lot. Wastewater contains contaminants like acids, bases, toxic organic and inorganic dissolved solids, and colors. Out of them, the most undesirable are colors caused mainly by dyes. Color and other compounds present in water are always not desirable for domestic or industrial needs. The wastes of dyes are predominant amongst all the complex industrial wastewater. This water is dark in color and highly toxic, blocking the sunlight and affecting the ecosystem. Among all the dyes, azo dyes contribute to commercial dyes used widely in textile, plastic, leather, and paper industries as additives. The removal and degradation of azo dyes in aquatic environment is important because they are highly toxic to aquatic organisms. For every industry, clean technology has become an important concern. In this chapter, the authors discuss about existing processes as well as promising new technologies for textile wastewater decolorisation.

The study investigates the effect of partial ozonation of textile wastewater, both at the inlet (pre-ozonation) and the outlet (post-ozonation) of biological treatment, for the optimization of COD and color removals, both typical polluting parameters associated with the textile industry. Pre-ozonation provides at optimum contact time of 15 minutes 85% color removal, but only 19% COD reduction. Removal of the soluble inert COD fraction remains at 7%, indicating selective preference of ozone for simpler compounds. Post-ozonation is much more effective on the breakdown of refractory organic compounds and on color removal efficiency. Ozonation after biological treatment results in almost complete color removal and a 14% soluble inert COD reduction. The polishing effect of post-ozonation also proves quite attractive from an economical standpoint, involving approximately 50% of the ozone utilization at the same ozone flux rate and contact time, yet providing a lower soluble residual COD level.

Industrial Sectors

Synthetic dyes are widely used in textile, printing, leather tanning, cosmetic, drug and food processing industries. The printing and dyeing industry is considered as one of the most polluting industrial sectors. The printing process is very versatile and includes printing on paper as well as printing on textile, plastic and other materials. After the printing process is completed, various chemicals such as ethers, alcohols, phenols, aldehydes, ketones, benzene, and esters are used in the cleaning procedure. Resulting wastewater often contains a variety of solvents, surfactants, dyes, and other chemicals, thus greatly increasing the difficulty of wastewater treatment. Improper discharge of printing and dyeing wastewater into water bodies will have several effect, beginning with aesthetical issues followed by destruction of the aqueous ecosystem due to light attenuation, oxygen consumption and toxicity effects. Therefore, it is very important to find out and optimize printing and dying wastewater treatment techniques. Processes for dye removal from wastewater can be physical, chemical, biological and more recently hybrid treatments. Physical processes such as adsorption, based on mass transfer mechanism, are commonly used method mainly due to ease of operation and high efficiency. Chemical processes including coagulation and flocculation, advanced oxidation processes and electrochemical treatment are usually more expensive due t chemicals use, equipment requirements and electrical energy consumption. However, these techniques are destructive and may lead to total mineralization of dye molecules and accompanying pollutants. Biological treatment is a low-cost and environmentally friendly process that produces less sludge. This method has significant advantages but dye molecules are less prone to this kind of treatment as they are made to be stable and reluctant. So, the adjustment and optimization of biological treatment, for dye removal, is an ongoing field of research. In recent studies hybrid processes are gaining more attention, combining different techniques. Integrating treatments, as a cost-saving and time-saving process, can represent optimal solution for printing wastewater treatment.

Synthetic dyes are widely used in the textile industry. Dye pollutants from the textile industry are an important source of environmental contamination. The majority of these dyes are toxic, mostly non-biodegradable and also resistant to decomposition by physico-chemical methods. Among new oxidation methods or "advanced oxidation processes", heterogeneous photocatalysis appears as an emerging destructive technology leading to the total mineralization of many organic pollutants. CI Basic Yellow 28 (BY28), commonly used as a textile dye, could be photocatalytically degraded using TiU2 as catalyst under sunlight. The effect of some parameters such as the initial catalyst concentration, initial dye concentration, initial NaCl and Na2CO3 concentrations, pH, H2O2 and type of catalyst on the degradation rate of BY28 was examined in details. The presence of NaCl and Na2CO3 led to inhibition of the photodegradation process. The highest photodegradation rate was observed at high pH, while the rate was the lowest at low pH. Increase of the initial H2O2 concentration increased the initial BY28 photodegradation efficiency. ZnO was a better catalyst than TiO2 at low dye concentrations.

Electrocoagulation method for textile dye wastewater treatment was investigated in this study. Results show that electrocoagulation can be used powerfully and effectively in organic matter degradation of textile industrial wastewater, where the extent of COD removal and decolorization are achieved about 75.45% and 84.62% after 25 minutes, respectively. pH for textile dye wastewater ascended higher than that of raw wastewater and temperature increased with electrolysis time. GC-MS spectra suggest that organic pollutants in textile dye wastewater are effectively oxidized and decomposed by direct current electrolysis. In addition, the quality of the upper layer liquid after electrolysis nearly meets the criteria of Discharge Standard of Water Pollutants for Dyeing and Finishing of Textile Industry (GB4287-92) of China.

The textile industry releases highly polluted and complex wastewaters, which are difficult to treat and require numerous treatment steps. Innovative technologies for on-site treatment at each factory would permit cost reduction. For this reason, we ran a laboratory-scale study to assess the suitability of a sequencing batch biofilter granular reactor (SBBGR) for textile wastewater treatment, testing four different types of wastewater. Results demonstrate that wastewater characteristics greatly affect the reactor efficiency. Hence, a pre-study is advisable to define the best operational conditions and the maximum treatment capability for the wastewater under analysis. Nevertheless, SBBGR is a valuable biological treatment, effective in the reduction of pollutant load with stable performances despite the variability in wastewater composition. Tests with ozone integration have demonstrated that it is possible to dose small quantities of ozone to obtain an effluent suitable for direct discharge. However, a dynamic ozone dosage should be used to optimize the process as the correct ozone dose strongly depends on the wastewater composition.

The aim of the present work was the development of a new biological method for the treatment of textile industry effluents, which is cheaper, more profitable, and eco-friendly. This method is essentially based on the synthesis of dye-fixing peptides. The use of peptides synthesized via a solid-phase synthesis to fix a reference textile dye like “Cibacron blue” (CB) and the performance analysis of binding assays were the main objectives of this study. For this reason, two peptides P1 (NH2-C-G-G-W-R-S-Q-N-Q-G-NH2) and P2 (NH2-C-G-G-R-R-Y-Q-P-D-S-NH2) binding with the CB dye were synthesized by the solid-phase peptide synthesis (SPPS) technique. The obtained results showed significant fixation yields of CB-peptides of 91.5% and 45.9%, respectively, and consequently, their interesting potential as a tool for a new biochemical method in the pollution prevention of textile wastewater.

Increased production in the textile industry has the potential to result in high dye waste water. Various conventional methods to handle with textile waste treatment have been done, but still considered not yet or less effective. The AOP technology (Advanced Oxidation Processes) applied in this research is a rapid degradation technology in textile wastes with advanced oxidation process through the formation of hydroxyl radical (OH) which is considered to optimize the degradation process of textile dye waste. This study aims to evaluate the performance of ozonation methods and AOP (O3/UV/H2O2) in dye degradation of textile wastewater containing remazol blue compounds. Both configuration methods used are optimized in several parameters such as waste flow rate, ozone voltage and pH to obtain maximum remazol blue degradation. From this study, the higher percentage to remazol blue degradation is 99.99%, which is achieved by AOP method, with double air injection air flow rate of 10 L/min and 0.25 L/min liquid flow rate.

Synthetic dyes are widely used in textile, paper, food, cosmetics and pharmaceutical industries with the textile industry as the largest consumer. Among all the available synthetic dyes, azo dyes are the largest group of dyes used in textile industry. Textile dyeing and finishing processes generate a large amount of dye containing wastewater which is one of the main sources of water pollution problems worldwide. Several physico-chemical methods have been applied to the treatment of textile wastewater but these methods have many limitations due to high cost, low efficiency and secondary pollution problems. As an alternative to physico-chemical methods, biological methods comprise bacteria, fungi, yeast, algae and plants and their enzymes which received increasing interest due to their cost effectiveness and eco-friendly nature. Decolorization of azo dyes by biological processes may take place either by biosorption or biodegradation. A variety of reductive and oxidative enzymes may also be involved in the degradation of dyes. This review provides an overview of decolorization and degradation of azo dyes by biological processes and establishes the fact that these microbial and plant cells are significantly effective biological weapon against the toxic azo dyes. Int.
