Solar energy being one of the most promising alternatives, this
because of its availability and low cost compared to other energies.
The device that uses solar energy to desalinate saline water is called
the solar still. The problem at the solar s
till is reflected in its low
efficiency, with the aim of raising it. This research presents a
theoretical and experimental study for single-slope and single-basin
solar stills.
Research topic includes the construction of a mathematical
model to study the effectiveness of the basic design of condensation
of steam plants to develop thermoelectric centers dedicated to the
production of electric power and water desalination.
To maintain
the thermal efficiency and maintain a minimum level of
contamination , has been in the current study compared the amount
of savings in consuming the amount of fuel as a result of the
process of co-production of electricity and desalinated water in the
proposed design, compared with the amount of fuel consumed as a
result of the separate electric power production and water
desalination process .In order to study the effect of this has been the
design and evaporative desalination unit and multi-effect unit gas
turbine and the basic termodinamics properties . the efficiency
measure to develop the basic design of the steam plant.
The rising in the world’s population leads automatically to the rising in water demand. As a consequence
the lack of drinking water increases Currently, approximately 1.2 billion people globally (one-sixth of the
world’s population) do not have acc
ess to adequate clean water. Since a large part of the world’s
population is concentrated in coastal areas, the desalination of seawater seems to be a promising solution,
especially in our Arab world. An innovative stand-alone solar desalination system could be used to
produce drinking water from seawater or any brackish water sources. The great advantage of such a
system is that it combines efficient desalination technology, reverse osmosis, with a renewable energy
source. The main goal is to improve the technical feasibility of such systems, There are many advantages
of this coupling with RE resources ; first of all we separate the drinking water from the electricity grid
and its faults, save burning the fossil fuel and its emissions, and provide fresh water to remote
communities that do not have sufficient traditional energy sources. But as we see in this study we don’t
have economic benefit; because these projects depend on the electricity cost in each country and the
location and its solar specifications.
We designed and implemented a small laboratorial model for PV-RO (Photo-Voltaic Powered Reverse
Osmosis) to recognize the performance for seawater and brackish water, we faced some problems such as
embargo on Syria; so have done project using affordable local potentialities, but we craved to keep the
principle of operation, so we make it for the tap water which close to brackish.
