“…In literature, the average volume of the photoreactors used for lab scale experiments ranged from 0.2 -2 L, while for pilot scale it is more than 2 L. Table 3 [32,36], whereas, Karabelas et al [63] employed special cylindrical photoreactor covered with aluminum (due to its greater reflectance of UV-A irradiation) and 4×24 W black light lamps were suspended over the solution.

“…Adsorption is more effective in acidic and alkaline medium. However in natural medium, no correlation has been shown between dark reaction adsorption and photocatalytic degradation [63].

“…The apparent rate constant of degradation increases with an increase in UV irradiance because more photons fall on the catalyst, which enhances production of hydroxyl radicals [63]. At low intensity of illumination, the degradation rate is of first order in intensity, while at high intensity, the reaction rate increases with the square root of the intensity level [86].…”

“…A number of studies have shown the dependence of photocatalytic degradation rate on the initial concentration of catalyst. Photocatalytic efficiency is found to increase with catalyst loading up to certain dosage and further increase results in a reduction of the removal rate (Wu 2008, Bouanimba et al 2011, Nezamzadeh-Ejhieh and Karimi-Shamsabadi 2014. At a certain point, although catalyst loading increases the number of active site, all the beam energy is attenuated within the reactor.…”

AbstractIn the past few years, there have been many researches on the use of different types of homogenous catalyst for the degradation of textile wastewater in conventional advanced oxidation processes (AOPs). However, homogenous AOPs suffer from few limitations, including large consumption of chemicals, acidic pH, high cost of hydrogen peroxide, generation of iron sludge, and necessity of post-treatment. Therefore, recently, there have been more researches that focus on improving the performance of conventional AOPs using heterogeneous catalysts such as titanium dioxide, nanomaterials, metal oxides, zeolite, hematite, goethite, magnetite, and activated carbon (AC). Besides, different supports such as AC that have been incorporated with transition metals and clays have been proven to have excellent catalytic activity in AOPs. This paper presents a comprehensive review of advances and prospects of catalytic AOPs for the decontamination of a wide range of synthetic and real textile wastewater. This review provides an up-to-date critical review of the information on the degradation of various textile dyes by a wide range of heterogeneous catalysts and adsorbents. The future challenges of AOPs, including chemical consumption, toxicity assessment, reactor design, and limitation of catalysts, are discussed in this paper. In addition, this paper also discusses the presence of ions, generation of by-products, and industrial applications of AOPs. Special emphasis is given to recent studies and large-scale combination of AOPs for wastewater treatment. This review paper concludes that more studies are needed for the kinetics, reactor design, and modeling of hybrid AOPs and the production of their corresponding intermediate products and secondary pollutants. A better economic model should also be developed to predict the cost of AOPs, as the treatment cost varies with dyes and textile effluents.

“…Since it is labeled as being at a high toxicity level and persistence, many technologies, for example, adsorption (Salem 2000), photo-catalysis (Bouanimba et al 2011), biotic and biochemical degradation (Ghaedi 2014) have been developed for the treatment of bromophenol blue. But these technologies have many disadvantages such as low efficiency, high cost and harsh operating conditions (Zhang et al 2010).…”

As an ideal anode material, Boron-doped diamond (BDD) has been widely applied in electrochemical oxidation of various organic pollutants, for its unique physical and chemical properties. In this paper, the authors studied the degradation of bromophenol blue through the electrochemical anodic oxidation by using the boron-doped BDD as the anode. The effect of statistically important operating parameters on treatment performance, such as treatment time, flow rate, applied current and concentration of supporting electrolyte, was evaluated by employing a factorial design analysis in terms of color removal and COD removal amount. As a result, the BDD technology was approved to be highly effective in treating bromophenol blue. Moreover, the results revealed the applicability and potential of factorial design analysis in operating parameters optimization and practical engineering application of BDD technology.
