Modified Inclined Solar Stills in passive (PISS) and active mode (AISS) were fabricated and researched in the environmental condition of Chennai, India. In an AISS, Spiral Tube Collector (STC) has been integrated for the extraction of drinking water. The major intention of the current research is to estimate the performance of the PISS and AISS for extracting fresh water from brackish water. The highest distilled water production from the PISS and AISS is 4.4 and 8.3 kg/day, respectively. Furthermore, water quality analysis for brackish water has been carried out. The obtained pH value of the brackish water is 8.7 and for fresh water are 7.6. The water qualities meet EPA standards.

在印度钦奈的环境条件下，制造并研究了被动（PISS）和主动模式（AISS）的改进型倾斜太阳剧照。在AISS中，已经集成了螺旋管收集器（STC）以提取饮用水。当前研究的主要目的是估计PISS和AISS从微咸水中提取淡水的性能。PISS和AISS的最高蒸馏水产量分别为4.4和8.3千克/天。此外，已经对微咸水进行了水质分析。获得的微咸水的pH值为8.7，对于淡水为7.6。水质符合EPA标准。
