| Tóm tắt: | Pure and fresh water is being scarce day by day. In spite of being a riverine country the
people of Bangladesh are not provided with sufficient amount of pure drinking water. A
large number of people including children and infants face severe water borne diseases
and many of them die. Solar still is a cheap, useful, non-toxic, clean and easy to made
renewable technology which can be used to provide pure water. The potential of solar still
is high in Bangladesh due to the climate conditions. Effectiveness of a solar still can be
analyzed from different point of views considering different parameters. Over the time
various modifications have been made and investigations have been done to find the
factors that enhance the performance of solar still. However, in our experiments initiatives
were taken to study the performance of a simple passive solar still having black colored
rocks as absorber medium. The objective of this paper was to find the effect of black
colored rock absorber medium on the performance of solar still during the presence of day
light and also during the period when the sun light disappeared. It has been observed that
using such absorber medium results in yield of pure water even after sun-set. |
