EXPERIMENTAL STUDY ON A STEPPED BASIN SOLAR STILL

In the present work an attempt has been made to improve the productivity of a single slope solar still by constructing many steps to the basin of the solar still. Experimental setup was fabricated and observations were taken in the premises of SHIATS Allahabad, U.P., INDIA. It is observed that productivity can be reached up to more than 6 liters per day for 1 metre square area of the basin when multi-wicks are added to the system. Overall increase in the production of stepped basin solar still using wick type arrangement in the basin is 20.5 % more than without using wick arrangement
