The Cost

By use of iron-carbon micro-electrolysis-UASB-SBR continuous process, treatment of an actual alkali dyeing wastewater (pH 11.50~13.50) taken from a certain factory in Xian-Yang was studied. The results indicated that: (1) When the influent COD is 1000~1600 mg·L-1, chroma 250 times, firstly effluent COD reduced to 400~800 mg·L-1and chroma 40 times by iron-carbon micro-electrolysis process, secondly effluent COD dropped to 250~500 mg·L-1by UASB process, finally effluent COD dropped to 70~98 mg·L-1by a SBR with loading PVA micro-gel beads, which meet the direct emission limits of water pollutants for dyeing and finishing of textile industry (GB 4287-2012); (2) Effective combination process of iron-carbon micro-electrolysis with UASB-SBR can be obtained through HRT optimization of micro-electrolysis reaction (HRT=10), that not only meet the requirement influent pH of anaerobic reactor, but also greatly reduce the cost of alkaline in practical application of iron carbon micro-electrolysis.

Abstract Wastewater from the textile industry containing a high concentration of organic and inorganic chemicals have strong color and residual chemical oxygen demand (COD). Therefore, advanced oxidation processes (AOPs) are very good candidates to treat textile industry wastewater. In this study, we investigated the effect of different types of AOPs supported with hydrogen peroxide (H2O2) on the treatment of viscose fibers dyeing wastewater. Fenton, photo-Fenton, and Fenton supported subcritical water oxidation (FSWO) processes were chosen as AOPs to compare the treatment efficiency of viscose fibers dyeing wastewater. The effects of solution pH, Fe2+ concentration, and H2O2 concentration on the treatment of viscose fibers dyeing wastewater were tested. The maximum color and COD removal efficiency was obtained corresponding to pH 2.5 for all oxidation methods when MB dye solution was used. However, the maximum efficiencies were obtained at pH 3.0 for real textile wastewater decolorization. The MB dye removal efficiency was increased to 97.22, 100, and 100% for Fenton, photo-Fenton, and FSWO processes, respectively, when the addition of H2O2 concentration was adjusted to 125 mg/L. However, the maximum color removal efficiencies of viscose fibers dyeing wastewater were obtained 56.94, 61.26, 64.11% for Fenton, photo-Fenton, FSWO processes, respectively. As a result, the FSWO showed maximum color removal efficiencies.

Textile Dyeing Wastewater

An environmental problem facing the textile industry is the coloured effluent from the dyeing of cellulosic fibres with reactive dyes. Reactive dye loss during dyeing operations is about 10 to 40 %, indicating the need to learn more about the fate of these dyes. Increasing environmental regulations are driving technical innovation to manage this problem. Good analytical techniques for the separation and detection of reactive dyes and their derivatives are necessary for monitoring dye-house effluent, as well as in the optimisation of dye synthesis, purification, formulation and application.

Textile Dyeing Wastewater

The textile industry, which produces toxic and low biodegradable wastewater, is a major industry of Taiwan. Thus, this study compared the performance of the membrane bioreactor (MBR) and sequencing batch reactor (SBR) process for treating real textile dyeing wastewater. The microbial diversity of the MBR process was also identified by a combined culturing method and molecular biotechnology. The results show that the removal efficiencies for color, COD, BOD, and SS with the MBR process were 54, 79, 99, and 100%, respectively, all higher than the corresponding parameters for the SBR process: 51, 70, 96, and 60%. All the above four parameters for the MBR effluent meet the criteria of the Taiwan EPA, while on the other hand for the SBR process, only color and COD meet the Taiwan EPA effluent criteria. Furthermore, the genus Microbacterium, especially the Microbacterium aurum, was the most predominant population, contributing 70.6% of the total isolates, and might be responsible for the degradation of the dyeing wastewater. Another two textile dyeing degradation bacteria, Paenibacillus azoreducens and Bacillus sp., as predominant bacteria in MBR sludge, were also observed.

Dyeing and finishing processes applied in the textile industry are the most common source of water pollution. The wastewater containing dyes is difficult to treat. The fly ash modified by alkali was investigated in this study to evaluate the removal efficiency of methylene blue in aqueous solution. The experimental results shown that the efficiency of adsorption could be prominent improved by alkali activated fly ash. Alkali activated fly ash could be an economical adsorbents used for printing and dyeing wastewater treatment processes.

Depth Interviews

This paper proposes a new conceptual framework in understanding the dynamics within the Kurdish and Turkish (KT) owned firms in London by utilising Charles Tilly’s work concerning collective resource mobilisation. Drawing on 60 in-depth interviews with restaurant, off-licence, kebab-shop, coffee-shop, supermarket, wholesaler owners and various community organisations, the paper sheds light upon the questions of why and how the KT communities in London moved into, and are over represented and why Turkish Cypriots are absent in small business ownership. The re-search illustrates that members of the KT communities aligned in their interests to become small business owners after the demise of textile industry in the midst of 1990s in London. The interest alignment in small business ownership required activation of various forms of capital and transposition of social, cultural and economic capital into one another.
