The present study was undertaken as part of the first application and evaluation of the BREF (Best Available Techniques; BAT Reference Document) Textile Document within the context of the European Union's Integrated Pollution Prevention and Control (IPPC) Directive to a large scale textile mill in Turkey. The BAT requirements for the denim manufacturing textile mill were selected in cooperation with the factory management. Detailed mass balance calculations were conducted to evaluate the overall effect of the selected BAT options. The initial findings indicated that the adoption of the selected BAT options resulted in considerable savings in water and energy consumption in the mill. Besides the installation of flow meters and use of semi-counter current rinsing in the most water-intensive processes, minimization of wash waters in the water softening plant, reuse of the concentrate stream from the reverse osmosis plant and compressor cooling waters provided a 29.5% reduction in the total specific water consumption of the mill, reaching the lower limits suggested by the BREF Textile Document. In terms of energy consumption, use of waste heat from finishing wastewater streams in heating up the wash waters, heat insulation and maintenance applications in addition to BAT measures taken for water minimization reduced specific energy consumption by 9% achieving the limits set by the BREF Textile Document.
本研究是在欧盟综合污染预防与控制（IPPC）指令框架下，首次将最佳可得技术（BREF）纺织文件应用于土耳其一家大型纺织厂并进行评估的一部分。与工厂管理层合作选定了牛仔布制造纺织厂的最佳可得技术要求。进行了详细的物料平衡计算，以评估所选最佳可得技术方案的总体效果。初步结果表明，采用所选的最佳可得技术方案使该厂在水和能源消耗方面大幅节省。除了在用水最密集的工序安装流量计并采用半逆流漂洗外，在水软化厂尽量减少洗涤水用量、回用反渗透厂的浓缩液流以及压缩机冷却水，使该厂的单位总水耗降低了29.5%，达到了BREF纺织文件建议的下限。在能源消耗方面，利用整理废水流中的废热加热洗涤水、进行隔热和维护应用，以及为尽量减少用水而采取的最佳可得技术措施，使单位能耗降低了9%，达到了BREF纺织文件设定的限值。
