The basin of the solar still is made water
tight to avoid water leakage and the inside surface is blackened to absorb maximum solar
radiation. It should probably be baked in the
sun for a while before it is used in order to free
the paint of any volatile toxicants which might
otherwise evaporate and condense along with
the drinking water. The bottom and sides of
the basin are insulated to reduce the heat losses
to the surrounding. The solar still has been
designed installed and operated at Faculty of
Engineering Technology at Al-Balqa
