When a solar-thermal power plant was being constructed near Lebrija, Spain in 2009, and with limited options for the supply of water, the responsible parties searched for a solution to feed the cooling towers with run-off from the surrounding agricultural fields. The downside of using this water was its poor quality, so concern was raised regarding the effects of using low-grade water for the cooling machines.
Having years of experience with such alternative methods…UET was up to the task, so was brought in during the design phase to create a system that would effectively treat the water going into circulation and allow the use of the recycled water in the cooling towers. At the same time, the UET system would eliminate the need to treat the effluent or require disposal of hazardous treatment chemicals.
After operating since 2010 with no major issues, the power company has saved hundreds of thousands of euros that would have otherwise been spent on water supply and traditional chemical treatment methods.
