Abstract: In this work, a stepped solar still and an effluent settling tank are fabricated and tested for desalinating the textile effluent. The effluent is purified in an effluent settling tank. In this tank, large and fine solid particles are settled and clarified. The settled effluents are used as raw water in the stepped solar still. For better performance, the stepped solar still consists of 50 trays with two different depths. First 25 trays with 10mm height and the next 25 trays with 5mm height are used. Fin, sponge, pebble and combination of the above are used for enhancing the productivity of the stepped solar still. A maximum increase in productivity of 98% occurs in stepped solar still when fin, sponge and pebbles are used in this basin. Theoretical analysis agrees well with experimental results.
