“…Alkaline solutions and surfactants can be used again in the mercerization process if suspended solids are removed using ultrafiltration (UF) process as the appropriate treatment method. [9] Membrane technologies have been widely recognized as an adequate option for wastewater treatment and reclamation because it can selectively remove contaminants from wastewater. [3,6,[10][11][12] Today, polymeric membranes are the most commercially used, [1] but ceramic membranes have higher thermal, chemical and mechanical stability compared to polymeric membranes.…”

Textile wastewaters are rated as one of the most polluting in all industrial sectors, and membrane separation is the most promising technology for their treatment and reuse of auxiliary chemicals. This study evaluates the performance of three types of tubular ceramic ultrafiltration membranes differing by mean pore size (1, 2 and 500 kDa) treating textile mercerization wastewater from a textile mill at different operating conditions: cross-flow velocity (CFV) and temperature. Acceptable results were obtained with 1 kDa ceramic membrane, with rejection efficiencies 92% for suspended solids, 98% for turbidity, 98% for color and 53% for total organic carbon at 20°C and 3 m s −1 CFV. Highest fouling effect was observed for 500 kDa membrane and lowest CFV. According to the observed results, 1 kDa membrane could be used for the treatment of wastewater from the textile mercerization process in terms of permeate quality. ARTICLE HISTORY

“…The use of its high temperature and air heat transfer can enhance the combustion air temperature, and reduce the exhaust temperature to achieve waste heat recovery purposes [65,66]. However, the textile industry is also a heavy consumer of water [42]. It is therefore evident that water recycling and reuse is also an important wastewater treatment issue [67].…”

Abstract:The textile industry is one of the world's major sources of industrial pollution, and related environmental issues are becoming an ever greater concern. This paper considers the environmental issues of carbon emissions, energy recycling, and waste reuse, and uses a mathematical programming model with Activity-Based Costing (ABC) and the Theory of Constraints (TOC) to achieve profit maximization. This paper discusses the combination of mathematical programming and Industry 4.0 techniques to achieve the purpose of green production planning and control for the textile industry in the new era. The mathematical programming model is used to determine the optimal product mix under various production constraints, while Industry 4.0 techniques are used to control the production progress to achieve the planning targets. With the help of an Industry 4.0 real-time sensor and detection system, it can achieve the purposes of recycling waste, reducing carbon emission, saving energy and cost, and finally achieving a maximization of profit. The main contributions of this research are using mathematical programming approach to formulate the decision model with ABC cost data and TOC constraints for the textile companies and clarifying the relation between mathematical programming models and Industry 4.0 techniques. Managers in the textile companies can apply this decision model to achieve the optimal product-mix under various constraints and to evaluate the effect on profit of carbon emissions, energy recycling, waste reuse, and material quantity discount.

“…The nanofiltration removes all the impurities and allows the passage of salt with the permeate stream. With the use of nanofiltration, the permeate (brine) can be recovered from the textile dyeing effluent [19,20]. The membrane filtration processes are effective for the removal of all types of pollutants including colour.…”

Submit Manuscript | http://medcraveonline.com IntroductionThe effluent generated from the industries is mostly treated using primary, secondary, tertiary and the advance treatment methods. The first step in the water pollution control is to minimize the pollution load in effluent that can be effected by preventing the raw materials or products from entering into the effluent streams. Segregation of highly polluting effluent stream from the low polluting stream followed by treatment of each effluent stream separately, gives better performance of the effluent treatment system [1]. In some cases, effluent of one industry can become the raw material of the other industries. For instance, the molasses (highly polluting effluent stream) generated from the sugar mill is used as a raw material in the fermentation (distillery) industry for production of alcohol. The second step in the effluent treatment is to collect and equalize the effluent streams that are discharged at different intervals from different stages of product manufacturing. The equalization ensures uniform characteristics in terms of pollution load, pH and the temperature. Screening and oil trap, prior to the equalization, is provided for removal of the floating solids or oil. The effluent is further treated in the primary treatment unit including addition of the coagulants such as lime, alum and polyelectrolyte followed by clariflocculator or flocculator and settling tank. Selection of the appropriate coagulants and doses of the coagulants are determined on the basis of the treatability study of effluent samples. The primary treatment helps in reduction of the total suspended solids (TSS). A significant reduction in biochemical oxygen demand (BOD) and chemical oxygen demand (COD) concentrations is also achieved. The primary treatment is followed by the secondary treatment i.e. aerobic biological treatment process and the settling, which further reduces BOD and COD concentrations in the effluent. The effluent with high BOD and COD concentrations, as in the case of slaughter houses and distilleries etc., two stage biological treatment system is preferred. Installation of an anaerobic (biomethanation) reactor prior to the aerobic treatment can facilitate recovery of methane gas and manure. The methane gas can be used as fuel in the boilers, fluid heaters and DG sets. The advance treatment technologies involving evaporation and incineration are also practiced. The advance oxidation and electrochemical coagulation process of effluent treatment have been explored for the treatment of industries.The treated effluents confirming to the prescribed standard can be discharged into inland surface water. Barring the effluents generated from tanneries, pulp and paper, textile industries and chemical industries, the effluent of some other industries can be reused for irrigation after treatment to the standards [2,3]. However, this mode of disposal is site specific and requires extensive monitoring of the soil and ground water quality. In India, Brazil and other countri...
