Experimental studies on quality of desalinated water derived from single slope passive solar still

The influences of climatic, operational, and design parameters on the performance of different solar stills configurations have been examined by many experimental and numerical studies to grasp the best design. The prime factors studied were solar radiation, glass cover tilt angle, latitude angle, depth of water level, and addition of dyes with the saline water. In this paper, an attempt has been made to study the correlations of physical and chemical properties of saline water used and desalinated water obtained from the single slope passive solar still. Water samples were tested in water testing laboratory available at Tamilnadu Water Supply and Drainage (TWAD) board, Chepauk, Chennai, India. The data obtained from the water samples analysis were correlated and the relationship between the various physical and chemical properties with Total Dissolved Solids was obtained. The correlation obtained could be used to predict the unknown water sample physical and chemical properties under the specified conditions. The study also finds that there is an improvement in the water quality obtained from the solar still.
