The main objective of the present work is to treat tannery effluent with a total dissolved content of 150 g/L using solar energy by humidification and dehumidification process using a roof even type greenhouse evaporator. This system not only helps to effectively treat the tannery effluent by increasing its total dissolved solids content to 350 g/L but also helps to generate potable water from tannery effluent by using solar energy. In this study, the performance of the effluent was tested in six different modes. It was found that the tannery effluent total dissolved solids content increased to 350 g/L in just 2.5 days when the greenhouse evaporator was operated in Mode 6 which is the shortest duration when compared to other modes of operation. The specific fuel consumption of the roof even type greenhouse system to treat tannery effluent is 22.55 kW h/ m³ which is 8.3% of the energy consumed by the zero liquid discharge plant. Meanwhile, the land area required to dehydrate 1 m³ of tannery effluent got decreased by 43% when the roof even type greenhouse evaporator was used.

本工作的主要目的是通过使用屋顶式温室蒸发器进行加湿和除湿工艺，利用太阳能来处理总溶解量为150 g / L的制革废水。该系统不仅通过将其总溶解固体含量提高到350 g / L来帮助有效地处理制革废水，而且还有助于利用太阳能从制革废水中产生饮用水。在这项研究中，以六种不同模式测试了废水的性能。结果发现，当温室蒸发器在模式6下运行时，制革厂废水中的总溶解固体含量仅2.5天就增加到350 g / L，这是与其他模式相比最短的时间。屋顶平整型温室系统处理制革废水的比油耗为22。³，这是零液体排放设备消耗的能量的8.3％。同时，使用屋顶均匀式温室蒸发器使1 m ³制革废水脱水所需的土地面积减少了43％。
