The escalation in demand for textile products increased the use of fresh water and treatment of wastewater; which escalates the search for suitable and energy-efficient technology for wastewater treatment. Solar assisted technology (i.e. solar desalination) for the textile industry wastewater treatment is proved to be an affordable technology. The only drawback of solar desalination is its low productivity which is the major hindrance in the global acceptance of the system. In the present study, an ingenious improvement in form of a parabolic concentrator-based solar desalination system (PCB-SDS) is designed to overcome low productivity, and the simultaneous use of source textile industry wastewater for its treatment makes this study more realistic. The performance of the designed system was examined for three different brine depths i.e. 20%, 40%, and 60% for two different processing step i.e. Dyeing and Degumming. System performance was evaluated in terms of energetic, exergetic, pollutant removal, and economic analysis. The maximum output of the system was found to be around 7440 and 8330 mL/day on clear sunny days with textile dyeing wastewater (TDyWW) and textile degumming wastewater (TDgWW) at 60% depth respectively. Daily average energy and exergy efficiency of system varies in the range 39.8–51.9 and 3.6–4.8% respectively. The degumming wastewater shows 85% COD removal, whereas, around 90% of TDS and hardness removal was also recorded. The dyeing processed wastewater showed 80% COD removal efficiency, ≅90% TDS, and hardness removal. The cost per liter of distillate output produced from designed PCB-SDS was found to be 0.014 $/L.

对纺织产品需求的增加增加了淡水的使用和废水的处理；这使得寻找合适且节能的废水处理技术的工作不断升级。太阳能辅助技术（即太阳能淡化）用于纺织工业废水处理被证明是一种经济实惠的技术。太阳能海水淡化的唯一缺点是其生产率低，这是该系统被全球接受的主要障碍。在本研究中，以抛物线聚光器为基础的太阳能海水淡化系统 (PCB-SDS) 形式的巧妙改进旨在克服低生产率，同时使用源纺织工业废水进行处理使这项研究更加现实。设计系统的性能在三种不同的盐水深度下进行了检查，即20%、40% 和 60% 两个不同的处理步骤，即染色和脱胶。根据能量、火用、污染物去除和经济分析来评估系统性能。在晴朗的晴天，纺织印染废水 (TDyWW) 和纺织脱胶废水 (TDgWW) 的深度分别为 60%，该系统的最大产量约为 7440 和 8330 毫升/天。系统的日平均能量和火用效率分别在 39.8-51.9 和 3.6-4.8% 的范围内变化。脱胶废水显示出 85% 的 COD 去除率，同时还记录了约 90% 的 TDS 和硬度去除率。染色处理废水表现出 80% 的 COD 去除率、≅90% 的 TDS 和硬度去除率。发现由设计的 PCB-SDS 生产的每升馏出物的成本为 0.014 美元/升。
