Fenton pretreatment has been used for treating dye wastewater. The effects of the dos of H2O2 and FeSO4, reaction time and pH on the removal COD were investigated. It was found that, when the reaction conditions are as follows: COD 2850 mg/L dyeing wastewater, the dosage of H2O2 is 140mmol/L, FeSO4 17.02 mmol/L, pH 7.6, and reaction time 1.0 h, the CODcr of dye wastewater removal rate of up to 70%. Fenton pretreatment process of dye wastewater has a broad prospect.

Dyes contain carcinogenic materials which can cause serious hazards to aquatic life and the users of water. Textile industry is the main source of dye wastewater which results in environmental pollution. Many studies have been conducted to investigate the use of low cost adsorbent as an alternative technique for the adsorption of dye. The objective of this study is to determine the potential of eggshell powder as an adsorbent for methylene blue removal and find out the best operating conditions for the color adsorption at laboratory scale. The adsorption of cationic methylene blue from aqueous solution onto the eggshell powder was carried out by varying the operating parameters which were contact time, pH, dosage of eggshell powder and temperature in order to study their effect in adsorption capacity of eggshell powder. The results obtained showed that the best operating condition for removal of methylene blue was at pH 10 (78.98 %) and temperature 50°C (47.37 %) by using 2 g of eggshell powder (57.03 %) with 30 minutes equilibrium time (41.36 %). The kinetic studies indicated that pseudo-second-order model best described the adsorption process.

The worldwide population is developing and along these lines, the world may event incredible freshwater shortage. Our water assets are lacking and, thus, water management and reusing techniques are the main choices for receiving freshwater later on decades. Accordingly, there is an incredible requirement for the advancement of proper, reasonable and quick wastewater. The common plan of this investigation is based on assessment and comparison, of the chance of apply advanced treatment techniques (Aeration process and Fenton oxidation process) for the exclusion of residuals organic pollutant present in Dye wastewater. The various procedures, which influence the compound oxidation, for colors in their fluid arrangements are considered by utilizing Aeration and Fenton's responses. These Processes are Aeration and Fenton Oxidation Process- (Hydrogen peroxide dose). Finally, EC, COD, BOD, Turbidity, TDS, TSS, and Phosphate, when the oxidation procedure is determined to guarantee the flawless obliteration of natural colors during their expulsion from wastewater. The Compared optimum conditions were 6ml/l of Fenton (H2O2) demonstrate that Fenton's oxidation procedure effectively accomplished excellent evacuation capability.

Textile industry is commonly use dyes in colouring process which become the major dye wastewater source that leads to serious pollution in the environment. The disposed dyes can lead to serious harm to the water users and life in the aquatic because of the dye properties. Hence, the dye adsorption by activated carbon prepared from foxtail palm fruit was studied. The objectives of this study were: 1) to prepare activated carbon from foxtail fruit palm and 2) to study the effect of contact time, adsorbent dosage and initial concentration of dye usage toward the efficiency of the prepared activated carbon. Nitric acid was used as activating agent in this experiment, with impregnation time of overnight and 500 °C of 2.5 hours carbonization. The adsorption capability of foxtail fruit palm activated carbon as activated carbon was determined with the use of a dye called methylene blue. The results showed that 5 g of activated carbon was used to reduce 97.1% of 2 mg/L methylene blue with 150 minutes contact time. This result aligns with the SEM result which indicated that the produce activated carbon is rich with well-developed and irregular size of pores ranging between 1.585 μm to 7.556 μm. This study indicates that activated carbon from foxtail palm fruits could be utilized as an alternative activated carbon to treat dye wastewater.

Abstract. Investigation on the degradation of dye simulated wastewater containing disperse H-GL dark blue was conducted under Fenton oxidation scheme. Reaction conditions such as the dosage of H2O2 and Fe2+, initial pH, initial dye concentration and reaction time were studied in terms of decolorization efficiencies. Up to 94.5% decolorization rate was attained after 30 min using H2O2 36 mg L-1 and Fe2+ 75mg L-1 at a pH of 3.

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.

From various aspects, enhancement effect of microwave and synergistic effect of the combined process were investigated systematically to treat dye wastewater using microwave irradiation-Fenton oxidation coupling coagulation process. The results showed when microwave was introduced to enhance Fenton oxidation and coagulation process, the degradation efficiency of refractory organic substances in dye wastewater was significantly promoted, and treatment time and various dosages of flocculant, oxidant and catalyzer were also reduced obviously. The synergistic effect discussion of the combined system also indicated that microwave irradiation brought not only the thermal efficiency but also the non-thermal efficiency, which would accelerate to produce more hydroxyl radicals, and promote the molecular polarization of organic substances. The physical and chemical properties of refractory organic substances in dye wastewater could be changed, which would be helpful for the follow-up Fenton oxidation and coagulation process. These facts fully embodied that there existed synergetic effects in microwave irradiation-Fenton oxidation coupling coagulation process.
