“…It suggested application potential of the reactor in the treatment of dyeing wastewater with various initial pH. N • + O •→ NO, (6) NO + O •→ NO , (7) NO + H O → NO + 2H . Figure 6 shows the change in conductivity during the MB degradation process and the MB degradation efficiency under different initial solution conductivities.…”

“…Dye molecules have complex and stable structures due to the existence of auxochromes (water soluble bonding compound) and chromophores (color giving compound) [3], which are toxic, recalcitrant, and difficult to be degraded by traditional physical, chemical, and biological treatment [4]. Advanced oxidation processes (AOPs) based on hydroxyl radicals generated in situ has attracted much attention [5,6]. The standard oxidation potential of hydroxyl radicals is as high as 2.80 V, only next to fluorine (E 0 : 3.06 V).…”

The degradation of methylene blue (MB) using an upgraded dielectric barrier discharge (DBD) plasma reactor was investigated in this paper. Air plasma was generated in the glass bead packed bed in the reactor, which was propagated into MB solution through a microporous diffuser plate. Microdischarge phenomenon can be observed on the interface of MB solution and the diffuser plate, where plasma active species were generated. The effects of air flow rate, initial solution concentration, initial solution pH, and initial solution conductivity on MB degradation were examined. Experimental results indicated that the proposed plasma reactor was effective for MB degradation. No obvious change in MB degradation efficiency was obtained for solution with various initial pH and conductivities, which suggested the potential of the reactor in actual wastewater treatment. The possible mechanism of the generation of plasma active species for MB degradation was proposed. In addition, the total organic carbon removal and chemical oxidation demand removal after 30 min treatment were 38.5% and 48.3%, which was higher than that obtained by ozone. The energy yield for MB degradation reached up to 9.3 g/kWh. Finally, a possible degradation pathway of MB solution was proposed.agents. As a promising plasma discharge mode, non-thermal plasma (NTP) technique can be utilized to degrade pollutants in wastewater at atmospheric pressure and room temperature with lower input energy than thermal plasma [8]. The typical NTP discharge in, and in contact with, liquids can be divided into three parts, namely, direct discharge in liquids, discharge in gas phase over a liquid, and discharge in multiphase environment such as bubbles or foams inside liquids [7].For discharge in gas phase over a liquid, the gas breakdown occurs in the gap between liquid and high voltage plate. Thus, plasma active species and high energy electrons are generated and then transferred into liquids to react with organic compound [9,10]. The efficiency of NTP reactors is mainly relevant to the efficiency of mass transfer between gas and liquid phases. A packed water jet bed plasma reactor was put forward by Foster et al. [11] to maximize the plasma contact area with the water. The parallel operation of multiple plasma jets or packed bed arrays of water streams are potential solutions to the scale-up problem. Tichonovas et al. [4] and Li et al. [12] proposed a dielectric barrier discharge (DBD) reactor and a gas-liquid plasma reactor, respectively. In their reactors, the gas was sent into the discharge zone, with plasma generated and dispersed into liquid phase by porous ceramic diffusers. This process can increase the efficiency of mass transfer of active species into liquid, resulting in enhanced degradation efficiency. However, the active species diffused into liquid are mostly ozone since the other active radicals dissipate during diffusion process due to their short lifetime [13]. Thus, the mineralization of contaminants in wastewater is difficult to achieve. Therefore, it ...

“…The second stream with high pH values is treated chemically (ozonation, electrocoagulation) and further reused in dyeing. The third 'high-loaded' stream is also purified using the coagulation-flocculation system, however, it cannot be reused [80]. The wastewater management system required carefully planned inventive activities that impacted on the company's innovation leader position.…”

“…Regarding this issue, there is a discussion on the primacy of GM fibers over IPM (integrated pest management) practices [79]. However, since wet processes are accountable for most of the water demand in the industry, one of the most sustainable solutions is a closed water circuit in textile dyeing plants [80] (p. 18). Another, however, more costly, solution involving the reuse of textile waste water is based on AOPs (Advanced Oxidation Processes).…”

The article is aimed at working out a comprehensive perspective on sustainable incremental change in organizations from a practice-based approach. That perspective presents everyday routine organizational practices as loci of sustainable organizational change. The research conducted reveals sustainability aspects that influence incremental change in the product development cycle in textile and apparel enterprises. The short life cycle of textile and apparel products challenges the multiplicity of sustainability aspects in that industry. The sequential procedure of mixing quantitative and qualitative methods was applied. A quantitative study was followed by qualitative research that was aimed at gaining an idiographic perspective. The statistical procedure was applied to determine the associative relationships between sustainable dynamizing factors and practice variability in textile and apparel enterprises. The influence factors were further explored as part of in-depth qualitative research. The qualitative research referred to three main aspects of sustainable practices at the initial production stage (sustainable water use), the last stages of the textile and garment life cycle (disposal and recycling of unwanted materials), and value (co)creation in the apparel industry. The results put emphasis on spontaneous vs. purposive activities in sustainable practice.
