“…Since 1980s, industrialization, urbanization, agricultural modernization, and population expansion have caused global freshwater demand to rise by around 1% (Natarajan et al 2022b). Solar Desalination removes salt from brackish or brine using solar energy (Thakkar et al 2020). The cycle of evaporation followed by condensation is the fundamental mechanism behind solar desalination, just as it is for the formation of natural rain.…”

Solar energy is widely acknowledged as a renewable and environmentally friendly energy source. Efficient storage of heat energy is a crucial challenge in solar thermal applications. Phase Change Materials (PCMs) have gained prominence due to their unique ability to store and release thermal energy through phase transition. The advantageous characteristic of PCMs is their low melting point, facilitating efficient heat storage and retrieval through latent heat of vaporization. This comprehensive review focuses on selecting suitable PCMs for diverse applications, considering their melting point and thermal properties. PCMs with high heat capacity and excellent solar radiation absorption are particularly favored in solar applications, especially for systems requiring large thermal energy storage (TES) capacities. In conclusion, this review underscores the importance of PCMs in solar energy applications, emphasizing their role in practical heat storage and release. By careful selection of PCMs based on melting point and thermal properties, the performance and efficiency of solar thermal systems can be optimized, contributing to a greener and more sustainable future.

The main objective of the present study was to desalinate seawater using Bacillus cereus gravel biofilm and cellulose acetate (CA) membranes with and without silver nanoparticles (AgNPs) as a potent and safe disinfectant for the treated water. Six desalination trials (I, II, III, IV, V and VI) were performed using the proposed biofilm/cellulose membrane. Results confirmed that Bacillus cereus gravel biofilm (microbial desalination) is the optimal system for desalination of seawater. It could achieve 45.0% RE (initial salinity: 44,478 mg/L), after only 3 h compared to the other tested treatments. It could also achieve 42, 42, 57, 43 and 59% RE for TDS, EC, TSS, COD and BOD, respectively. To overcome the problem of the residual salinity and reach complete elimination of salt content for potential reuse, multiple units of the proposed biofilm can be used in sequence. As a general conclusion, the Bacillus cereus biofilm system can be considered as remarkably efficient, feasible, rapid, clean, renewable, durable, environmentally friendly and easily applied technology compared to the very costly and complicated common desalination technologies. Up to our knowledge, this is the first time microbial biofilm was developed and used as an effective system for seawater desalination.

“…Indeed, this problem is partially handled by some technologies associated with water reuse and desalination [9,10]. Solar-powered desalination technologies [11][12][13][14][15][16][17] permit the sustainable supply of potable water and fossil energy saving. The sustainability of such desalination technologies is assessed in several interesting works [18][19][20][21][22][23].…”

Experimental Performance Investigation of an Original Rotating Solar Still Design under Realistic Meteorological Conditions

This research article proposes a novel design of solar still; furthermore, it investigates, experimentally, its thermal and productivity performances, as well as its efficiency, under the realistic meteorological conditions of the city of Gafsa, Tunisia (34.4311° N, 8.7757° E), in terms of ambient temperature and solar irradiance. The novel proposed design presents a cylindrical solar still with a rotating transparent plastic (Plexiglass) cover, wiped continuously on the inner surface. A specific technological configuration of the evaporation and condensation compartments is elaborated. A real prototype is manufactured in order to carry out the performance experimental investigation. A performance comparison is carried out between the cylindrical transparent plastic cover rotating and it being fixed, for two experimentation days presenting slightly different meteorological conditions. The experimental water and plastic cover temperatures, the hourly and the cumulative water production, as well as the hourly efficiency are deeply quantified and interpreted.
