The present investigation elucidates the effect of different absorbing materials in the single slope solar still (SSSS). The said absorbing materials are Polyvinyl Alcohol (PVA) sponges, pebbles, spherical clay balls (SCB) and CuO nano-coated absorber plates (CuO-NCAP). The experiment has been conducted in the following ways: (i) SSSS with PVA sponges, (ii) SSSS with pebbles, (iii) SSSS with SCB, and (iv) SSSS with CuO-NCAP. This research also investigated the night water collection of all individual experiments. Four identical SSSS were designed with 0.50 m2 collector area each and the four absorber types were tested in the same climatic conditions of Chennai (13.0821°N Latitude & 80.2702°E Longitude) during the period of April to June 2018. Physical and chemical water quality tests were conducted for the feed water (well water) and treated water from the SSSS. The productivity of SSSS-PVA sponges, SSSS-pebbles, SSSS-SCB and SSSS with CuO-NCAP are 1.9 L/m2.day, 2.8 L/m2.day, 2.6 L/m2.day, and 2.9 L/m2.day respectively. The cost of water distilled by SSSS with PVA sponges was approximately $0.0120/L. Similarly, it was $0.0073/L for SSSS with pebbles, $0.0080/L for SSSS with SCB and $0.0077/L for SSSS with CuO-NCAP.

合理的脱盐:研究太阳能蒸馏器中的合理储热材料
本研究阐明了单斜面太阳能蒸馏器(SSSS)中不同吸收材料的影响。所述吸收材料是聚乙烯醇(PVA)海绵,卵石,球形粘土球(SCB)和CuO纳米涂覆的吸收板(CuO-NCAP)。该实验已通过以下方式进行:(i)带有PVA海绵的SSSS,(ii)带有卵石的SSSS,(iii)带有SCB的SSSS,以及(iv)带有CuO-NCAP的SSSS。这项研究还调查了所有单个实验的夜间集水情况。用0.50 m 2设计了四个相同的SSSS在2018年4月至2018年6月期间,在钦奈(13.0821°N北纬度和80.2702°E东经)的相同气候条件下对每种集热器区域和四种吸收器类型进行了测试。对进水进行了物理和化学水质测试(井水)和SSSS处理过的水。具有CuO-NCAP的SSSS-PVA海绵,SSSS-卵石,SSSS-SCB和SSSS的生产率分别为1.9 L / m 2 .day,2.8 L / m 2 .day,2.6 L / m 2 .day和2.9 L / day m 2 .day分别。SSSS用PVA海绵蒸馏水的成本约为$ 0.0120 / L。同样,带卵石的SSSS为$ 0.0073 / L,带SCB的SSSS为$ 0.0080 / L,带CuO-NCAP的SSSS为$ 0.0077 / L。
