Development and evaluation of solar still with an internal heater

Abstract EN

A basin type-inverted V- transparent polyethylene cover solar still with an internal heater having an effective base area of 2m2 has been constructed and operated in Al-Zubair semi arid zone.

The unit was scheduled to provide fresh water from groundwater having average total dissolved salts of 5000 ppm.

An experimental study was carried out to evaluate the effect of using an internal heater on the performance of the still.

The effects of climatic and continuous day and night modes have been investigated and the effects of these conditions on the production rate of distillate have also been presented.

The results showed that combining an internal heater with basin type solar still caused a much higher yield than that of the simple solar still.
