Correction: Enhancing solar still performance with Plexiglas and jute cloth additions: experimental study

Influence of wick pile of jute cloth on distillate yield of double-basin single-slope solar still: Theoretical and experimental study

The lower productivity of square pyramid solar still is the prime impediment to its worldwide applicability. An attempt has been made to improve the productivity of square pyramid solar still utilising the novel augmented technique – funnel integrated with wick material. The funnels were attached to the basin of the solar still, and one end of the wick material was spread over the upper portion surface of the funnel, while the other end was dipped into saline water in the basin. At 1, 2 and 3 cm water depth, the impact of wick materials (black colour-painted jute cloth, black melton wool and black cotton cloth) and upper portion surface inclination angles of the funnel (15°, 20° and 25°) was investigated. For each case, three sets of experiments were carried out for three days in a row with four alike square pyramid solar stills under the weather conditions of (20.61° N and 72.91° E) in the winter season. The maximum productivity was achieved: 2.1432 L/m2 at 3 cm and 2.5368 L/m2 at 1 cm for still with funnel surface inclination angle of 25° for black cotton cloth and black melton wool and 2.8032 L/m2 at 1 cm for still without funnels for black colour-painted jute cloth.
