solar pond is a good device for solar heat energy storage that stored in its salt water depend on its clean surface .
Dear Dr. Khaleel
You have to cover the pond because there are many things in addition to dust as trees leaves ..etc, can harm the salt gradient pond. The problem is you cant but any thing and mix the waters then the gradient will finish. In large areas pond you can divided it to section and each one has a separate cover.

Dear Prof. Abass
You don't need to protect the salty water surface from dust as it is covered by a less salty water and with a lye of fresh water. You mean how to protect the solar pond from dust as it suspends in water and reduce the solar radiation received by the pond and reduce the collected heat. To protect the solar pond from dust you have to make a transparency cover that can cover all the pond surface at night and dusty weathers.

Dear Prof . Miqdam
i will like to thank you for your answer and idea for using a transparency cover to cover the solar pool but if the pond area is large .

Dear all
The solar pond are often in full salts areas and have little dust, but in the case of making one in an area where there are dust prefers be divided into rectangular areas and placed hoods her only at night to protect them from dust either in the case of the day, the amount of dust is not so influence the the efficiency of the storage process.

You could use a a light layer of floating silicon-based surfactant that collects the dust and can be skimmed periodically via a suction pump.
Hope this helps answer your question.

Dear Yehia
But this layer of silicon will reflect solar radiation.

Raid
Dear Raid,
As dust gets collected on the surfactant, this layer will become opaque and absorbs solar radiation instead of reflecting it.
Hope this helps answer your question.

Dear Dr raid
The transparency cover must has the ability to transfer solar radiation through it without absorbing a part of it.
