Abstract
This study presents a new and innovative suggestion to design a solar water desalination system by the direct
passive method, with the aim of raising productivity by recycling the energy lost during the desalination
process and raising the efficiency of condensation. In this study, the innovative design was evaluated to
demonstrate its ability to increase the productivity of direct passive solar desalination while maintaining
simplicity of installation and ease of operation. A prototype of the design was built to make a detailed study
on the efficiency of the design and its ability to raise productivity under several different operational and
climatic conditions in the city of Aden - Yemen, where several experiments were made to desalinate seawater
taken from the city's coasts and the water of semi-salty wells in the city of Aden to compare the readings
different. The results prove that the innovative design can raise productivity up to 80% higher than normal.
The effect of pond water depth and salinity on productivity was studied. The results show that the higher the
water depth in the evaporation basin, the higher the production capacity, and the higher the water salinity, the
lower the production capacity of inactive direct solar desalination systems. This study also provides an
assessment of the quality of the water produced by the innovative design by carrying out several chemical
tests and making a comparison with the water quality before desalination to ensure that the design is capable
of desalinating seawater or semi-salty well water to produce potable water. The results were confirmed for
the quality of the produced water, which confirms the ability of the design to produce potable water in
accordance with local and international standards, as the amount of total dissolved salts in sea water before
desalination was 41340 mg/L and in well water 1300 mg/L, while after desalination by innovative design The
total dissolved salts in treated sea water was 210 mg/L and in treated well water was 34 mg/L.
