Our field tests were conducted about 19 miles south of Dubai (United Arab Emirates) in a research area. During the testing period the average temperature ranged between 102F and 109F. At night, the temperature fell by only a few degrees. The metrological sunrise was at 3:26 with sunset occurring shortly after 17:00.
The goal of our tests were:
- Daily determination of the amount of drinking water produced.
- Bacterial and chemical analysis of the obtained drinking water to ensure purity.
- Formstability of the units under the heavy sunlight and heat (up to 65°C)
- Examination of the units to determine the effects and resistance of UV rays during long periods of exposure.
By the collection of condensation and the draining, the drinkable waterwas collected from all 3 units. The collecting ring enclosing the ground units served as a collecting device to the obtained drinking water from a pipe connection to the next connected unit and from there to lead in the waste container.
Operation of the system:
Every day the units were supplied with a new source of undrinkable water. One source of water was from a nearby lagoon. The water from the lagoon had a salt content of 23.5 dS / m. This water was not safe for human consumption. The temperatures averaged 107F and a humidity of 70% to 85%.
Each day we prepared large quantities of water which were analyzed for bacterial and salt content. It was found that the salt content was reduced by 95%, which is considered to be clean, safe drinking water.
During the tests, temperatures inside the system were recorded as high as 154F. These high temperature proved to have no negative affects on the stability of the components. The floor pan, the pyramid structures and the inter-connections all successfully met the requirements or performing in a desert region.
The materials manufacturer warrants the products used and GFI will continue to conduct our own long term testing and research as to the effects of UV exposure.
