...Roman Bader; Andrea Pedretti; Aldo Steinfeld A large-span solar parabolic trough concentrator is designed based on a multilayer polymer mirror membrane mounted on a rotatable concrete structure. The multilayer membrane is contained in a transparent protective air tube and generates a multicircular...

..., the integration of photocatalysis with a membrane separation process is studied in order to analyze the possibility of enhancing the efficiency. It is experimentally shown that for the integrated process, the rate of disappearance of a model pollutant (4-chlorophenol) is highly improved. Then it is demonstrated...

... solution. The desalination of brackish water at a TDS value of 3,000 ppm requires an energy of approximately 1.5 kWh/m 3 . For seawater at a TDS value of 34,000 ppm, this value increases to 9.5 kWh/m 3 . The selected type of membrane, the system design, and, in particular, the efficiency of the high...
