Technical and economic criteria were used to evaluate the feasibility of the treatment of an industrial effluent (10 m/h) for water recovery and reuse. The treatment evaluation included the following: (1) effluent characteristic determination; (2) selection and evaluation of the effluent treatment at lab scale, establishing operating conditions and process efficiency; (3) scaling up the treatment process to the industrial level; (4) treatment plant design and commercial availability analysis of the required equipment; and (5) the costs of the inversion and operation of the plant treatment, cost/m for water recovery, and time of investment recovery. The physicochemical characteristics of the effluent exposed the polluted wastewater with sodium chloride salts and colourants, predominating a mixture of tartrazine, Red 40, and brilliant blue from the synthesis of food additives. Other contributions of organic compounds and salts could be in minor content. According to the effluent conditions, a coupled process, integrated with ozonation and reverse osmosis, was indicated to be a treatment for water recovery. Scaling up the plant treatment design resulted in 130 m of area, producing 7.7 m/h of clean water. The cost of the effluent treatment was 1.4 USD/m, with an inversion return of 3.4 years and cost investment of USD 860,407. The treatment process resulted a viable project for water recovery.
采用技术和经济标准评估处理工业废水（10立方米/小时）以实现水回收和再利用的可行性。处理评估包括以下内容：（1）废水特性测定；（2）在实验室规模下对废水处理进行选择和评估，确定操作条件和工艺效率；（3）将处理工艺扩大到工业规模；（4）处理厂设计以及所需设备的商业可用性分析；（5）工厂处理的投资和运营成本、水回收成本/立方米以及投资回收时间。废水的物理化学特性表明该污染废水含有氯化钠盐和着色剂，在食品添加剂合成过程中，酒石黄、红色40和亮蓝的混合物占主导。有机化合物和盐的其他成分含量可能较少。根据废水状况，一种结合了臭氧化和反渗透的耦合工艺被认为是一种水回收处理方法。扩大后的工厂处理设计面积为130平方米，产水量为7.7立方米/小时。废水处理成本为1.4美元/立方米，投资回报期为3.4年，投资成本为860,407美元。该处理工艺是一个可行的水回收项目。
