Textile Wastewater Treatment

Textile wastewater must be effectively treated with the best available technology prior to release to receiving water bodies to prevent its impact on the environment. Apparently, membrane distillation shows great potential in treating textile wastewater a part of the complexity of the textile wastewater composition. This membrane process enables the water vapour to pass through its porous hydrophobic membrane and retains the concentrated pollutants to be transported. This paper provides data and information from previous studies using membrane distillation to treat textile wastewater. An overview of the development of membrane distillation as well as the fundamental theory is presented. Recent progress in the application of membrane distillation in textile wastewater is then discussed. The final part of the paper looked at the future orientation of this technology to be acceptable in the industrial sector, especially for the textile industry.

Membrane Wetting

The textile industry is an important contributor to the growth of the global economy. However, a huge quantity of wastewater is generated as a by-product during textile manufacturing, which hinders the ongoing development of textile industry in terms of environmental sustainability. Membrane distillation (MD), which is driven by thermal-induced vapor pressure difference, is being considered as an emerging economically viable technology to treat the textile wastewater for water reuse. So far, massive efforts have been put into new membrane material developments and modifications of the membrane surface. However, membrane wetting, direct feed solution transport through membrane pores leading to the failure of separation, remains as one of the main challenges for the success and potential commercialization of this separation process as textile wastewater contains membrane wetting inducing surfactants. Herein, this review presents current progress on the MD process for textile wastewater treatment with particular focuses on the fundamentals of membrane wetting, types of membranes applied as well as the fabrication or modification of membranes for anti-wetting properties. This article aims at providing insights in membrane design to enhance the MD separation performance towards commercial application of textile wastewater treatment.

ABSTRACT The Ship Escort Response Vessel System (SERVS) of Alyeska Pipeline Service Company (Alyeska) in Valdez Alaska is responsible for overseeing the prevention, preparedness, and response activities for the safe transportation of oil through Prince William Sound. Since the inception of SERVS in 1989, escort vessels have accompanied laden tankers through Prince William Sound from the Valdez Marine Terminal to the Gulf of Alaska, a distance of approximately 70 miles. The tankers pass through the pristine Prince William Sound, which encompasses over 2,500 square miles, with fjord-like topography and a subarctic climate. The evolution of the tanker escort system began with the emergency order issued by the state of Alaska in 1989 immediately after the grounding of the Exxon Valdez. A fleet of 12 vessels, each singular in purpose, was quickly developed: three dedicated pairs of escorts (comprised of an escort response vessel and tug), response barge standby vessels, and four dedicated docking tugs. The emphasis was more on oil spill response than prevention, and there was little interchangeability between vessels and their missions. In subsequent years, a variety of factors has caused changes to the escort system and vessel mix. These included the Disabled Tanker Towing Study, Prince William Sound Risk Assessment Promulgation of Federal Escort Requirements, oil spill response responsibility in the Gulf of Alaska, tanker vapor recovery, reduction in pipeline throughput, and weather restrictions. Additionally, industry instituted voluntary measures such as ice scouts and sentinel standby escorts for inbound tankers in ballast have affected the escort system, in addition to the experience gained in the operation the system. As the escort system matured, there was a marked emphasis and focus on oil spill prevention, fleet modernization, and multipurpose vessels to increase capabilities while maximizing efficiencies. Alyeska/SERVS embarked on a dedicated strategy to upgrade the specialized vessel fleet of 12 vessels to a fleet composed of fewer multipurpose vessels. This strategy encompassed a technological and operational enhancement of the fleet, significantly improving the prevention posture while maintaining the necessary response capabilities. Today, the Alyeska/SERVS escort fleet consists of nine multipurpose vessels. The cornerstones of the escort fleet are the two 10,192 horsepower Voith Schneider enhanced tractor tugs and the three 10,192 horsepower ? drive Prevention and Response Tugs, all specifically designed, constructed, and outfitted for tanker escorting. The combination of these vessels for tanker escorting utilizes complimentary best available technology to ensure the safe transit of tankers through Prince William Sound.

Membrane Distillation (MD) is a promising technology for separation and purification processes. It is a thermally-driven separation process which allow only vapour molecules are to pass through a porous hydrophobic membrane. MD separation is driven by the vapour pressure difference existing between the porous hydrophobic membrane surfaces unlike normal membrane processes which operate on temperature difference. This paper focus on the expectation of MD treatment process primarily for the readers who have no idea about this membrane process A brief overview is given of MD before treatment process which includes membrane materials, membrane preparation techniques, membrane characteristics, module and configuration. Membrane performance during treatment process will be highlighted. Membrane fouling which is one of the major drawback of MD will be also discussed.

Textile Wastewater Treatment

Dye chemicals from the textile industry are a principal source of environmental pollution. The industrial effluents must therefore be treated before their release into the aqueous environment. However, application of conventional biological methods for textile wastewater treatment is limited by unsatisfactory degradation of the refractory dyes and associated chemicals. In the present study a complete degradation of selected azo- and thiazine-dyes has been achieved by TiO2-solar photocatalytic oxidation (SPO). Here the SPO is accompanied by a reaction of dye sensitization. Enhanced degradation of colourless refractory pollutants has been observed in the combined process. The main advantage of the combined approach is the utilization of visible light for assisting the degradation of refractory organic pollutants, not only coloured, but also colourless, which cannot be photosensitized in the visible region. Although very little is known on the subject, the present results demonstrate that the process is promising for the removal of undesirable toxic chemicals from textile industry wastewater. To simulate such conditions we have recently studied the dye photosensitized solar photocatalysis of an uracil derivative. Both UV and visible light are required for enhanced substrate and dye decomposition. Irradiation by UV alone decreased the degradation rate of dye, while visible light alone did not lead to any decomposition at all. It seems that the mechanism of the studied reaction involves a combination of oxidation by hydroxyl radicals, via the hole-electron semiconductor route, with oxidation by singlet oxygen.

The capacity and mechanism of mono and bi-functional reactive dye adsorption utilizing a new adsorbent obtained from the dried residual sludge (~10% w.w.) of a textile wastewater treatment system was studied. With the focus on determining the efficiency of the adsorbent in the dye removal, the adsorption isotherms were determined for the reactive dyes RR2 and RR141, at different temperatures and salt concentrations. The experiments were carried out in fixed bed adsorption columns, which were defined as the best adsorption experimental condition for both of the dyes through the parameter qm (mg/g), obtained by the adjustment of Langmuir isotherms. Breakthrough curves for the dyes RR2 and RR141 were obtained varying the height to which the fixed bed columns were packed with adsorbent (15, 30 and 45 cm) and varying the adsorbate feed rate in the column (8, 12 and 16 ml/min). For the dye RR2 the maximum adsorption capacity was 53.48 mg/g and for the dye RR141 it was 78.74 mg/g.

Abstract The importance of water recovery and reuse is increasing day by day. Therefore, the use of advanced technologies is applied for the treatment and recovery of textile wastewater. The fact that ceramic membranes are resistant to the challenging characteristics of textile wastewater makes the use of ceramic membranes useful. Within the scope of this review, general information about the textile industry and treatment techniques are mentioned, as well as the properties of ceramic membranes and textile wastewater treatment. In the literature review made in this study, recent studies on the production of ceramic membranes and laboratory applications have been compiled. However, it has been observed that although the real-scale studies are relatively higher in industries such as the food and petrochemical industry, it is rather limited in the textile industry.
