Abstract: In the present work, an attempt has been made to determine the best absorbing material in the basin of pyramid wick-type solar still to produce high distillate yield.Three different absorbing materials viz., jute wick, sponge and charcoal have been selected and used in the basin of the still and the corresponding productivity has been measured.Among these absorbing materials, jute-wick in the basin has produced high distillate yield due to the low thermal capacity of the still.Jute wick is spread over the four tilted portions orienting towards north, south, east and west inside the still with saline water in the middle of the basin.The capillary action of the jute wick kept the wick surface wet throughout the working hours of the day with very low thermal capacity.It has been observed that, the total distillate yield over 24 hr cycle of 3.25, 3.19 and 4.5 lit/day for charcoal, sponge and jute wick respectively.
