The purpose of this effort is to develops new experimental set-up and improvement in the efficiency of a wick
type single slope solar still with advanced distillation system. In the construction and operation the auxiliary
arrangement is used to supply pre-heated water in a copper tube with black coated plate and reflector (mirror) also
addition of gravel’s at the bottom of basin as shown in Fig.1 By doing this arrangement there is definite addition of
latent heat of vaporization into the basin water, this increase of heat increases evaporation rates of vapor. More the
vapor escapes and stick to the glass cover and maximum will be the distillate through trough and collected in the flask.
The water produced by this advanced distillation system is the pure, clean and fresh water (i.e. can be used for food
cooking, bathing and consumption etc.)
