The SOWΛRLΛ SUN system is based on an innovative process, which has been designed within the scope of extensive scientific studies and tests. It comprises a patented solar receiver design, a sophisticated control system and an energy-efficient catalyst separation and recycle system. The system was successfully tested on the degradation of a variety of oxidizable compounds. As a first full-scale application, the elimination of hazardous compounds from a biologically untreatable cooling water was realized in a demonstration plant at the DLR location in Lampoldshausen. Originally, UV-lamp technology was used to purify the contaminated cooling water - a purification principle that caused high operation and maintenance costs. Today, the demonstration plant is run under continuous operating conditions and available to the expert community as a reference project.
