“…The heat generated by the NPs is used to evaporate the wastewater/seawater for reuse. Nano energy (NPs + solar energy) have been used to evaporate the wastewater for desalination [37,39,65,68,69,73]. These nano-enabled materials shift attention back towards the traditional solar-evaporation systems, simply called "solar stills" (SSs) [5-9, 11-13, 40, 42, 46, 53, 55] capable of producing more than 5 l/m 2 day [9,11].…”

Solar energy is one of the most powerful sources for many sustainable applications. Recently, efficient water distillation has attracted significant attention. The fresh water productivity depends on how efficiently the system harvests the incoming solar energy and converts it into useful heat. In the present work, nano-coated absorber plates (NCAPs) were examined in the single slope solar still (SSSS) for clean water production. The NCAPs were CuO, MoO 3 and ZnO, respectively. The CuO-NCAP was fabricated with the thermal evaporation method while the radio-frequency Magnetron Sputtering technique was used to fabricate the MoO 3 and ZnO NCAPs. The attained particle size of the CuO, MoO 3 and ZnO are 30-34 nm, 25-30 nm and 30-35 nm, respectively. The sphere (CuO), plate (MoO 3), and wedge (ZnO) like morphologies are identified with field emission-scanning electron microscope. All the NCAPs and reference solar still were tested under the same environmental conditions. The climatic parameters (solar influx, ambient temperature and wind) and SSSS's temperatures including water temperature (T w), internal air temperature (T int-air), inner cover (T ic), outer cover (T oc), and absorber plate temperature (T NCAP) were measured at 30 min intervals with the help of Type-J thermocouples. Herein, we present an evaporative heat transfer (h ew), efficiency, and cost analysis of the SSSS with CuO, MoO 3 and ZnO-NCAPs. Three different feed waters fetched from the surface well water, hill side well water and hill side pond water were used in this work for evaporation. The result reveals that the evaporation of conventional single slope solar still, CuO, MoO 3 and ZnO NCAPs were 2.1 l/m 2 day, 2.9 l/m 2 day, 2.7 l/m 2 day and 2.6 l/m 2 day, respectively.

“…Anodic alumina may also be used for the production of alumina nanowires [10]. Also, the alumina membranes have been used to fabricate biosensors, gas sensors and in tissue engineering applications, as well as for water desalination [11][12][13][14][15]. These membranes are also used to separate the E-coli bacteria from water [16].…”

Nanoporous anodic alumina (NAA) membranes were produced by anodizing process using commercially pure aluminium (1050 alloy). The optimization of processing parameters, such as applied potential, temperature and time in two different electrolyte solutions, has been performed to produce the ordered alumina nano-membrane. Nanoporous anodic alumina membrane (NAAM) was obtained by removing the aluminium substrate and opening the bottom of the pores. The microstructure of samples was studied and analysed by field emission scanning electron microscopy (FESEM). Image processing of FESEM pictures was performed with MATLAB. The results showed that at the optimum conditions of anodizing, the percentage of porosity and ordering of pores in the samples were similar to the productions of the high purity aluminium base. NAA layers that formed in sulphuric acid solution in comparison with oxalic acid had lower pore diameter (20 nm), lower inter-pore distance (45-50 nm) and higher hardness (325 HV). The optimized membranes which have been produced with the same thickness were used for separation of Coliform bacteria from the secondary clarified wastewater. The results showed that these membranes can be used as selective filters because of their desirable physical properties.
