Emerging Water Recovery Processes from Dew and Light Rain

Water recovery from dew is one of the smartest methods of water supply in remote places, particularly deserts. It relies on modern surface science and technology for the design of super hydrophobic tilted surfaces. The chapter will first summarize the physicalDew physical characteristic, chemicalDew chemical characteristics and biological characteristicsDew biological characteristics of dew. Then past and present methods of recovery of water from dew will be discussed together with recent findings on the design of patterned super hydrophobic surfaces and their uses for dew waterDew water recovery. Harvesting light rainfallsLight rain physical characteristics, which share with dew many physicalDew physical characteristic, chemicalDew chemical characteristics and biological characteristicsDew biological characteristics, is also considered in this chapter.
