Abstract Direct Solar Steam Generation (DSSG) system is an emerging technique in the field of desalination for yielding sustainable clean water. This investigation propagates through the use of nanoscale absorbers (montmorillonite) for sturdy desalination because of their excellent photo thermal conversation of nanoparticles. The solar absorber was dispersed in sea water in liquid type rather than fixed or floating type. Nanoparticles of chemical composition were employed by the researchers from starting to the present day, which includes carbon nanotubes, graphene oxide, etc. Inspired by nature and keeping in mind an eco-friendly technique, here we considered montmorillonite clay nanoparticles of natural origin. The experiment was conducted for an operational period of 14 days with a yield of 5.33–6.45 kg/m2/day with an evaporation rate of 0.70, 1.42 and 4.47 kg/m2.hr under 1-, 2- and 4-sun irradiance. The clean water output parameters was validated with WHO standards to satisfy potable water characteristics. The water characteristics before desalination for turbidity, pH, and Cl–, Na+ and TDS were found to be 48.50, 8.7, and 18,400, 12,120, 20,400 mg/L respectively; after desalination they were found to be 0.30, 6.65, 12, 4.5 and 52 mg/L respectively. This work focuses on current water scarcity problem and suggest a way to survival by using naturally available, low cost material.

Clean water scarcity is still an intense, prolonged global issue that needs to be resolved urgently. The solar steam generation has shown great potential with a high energy conversion efficiency for clean water production from seawater and wastewater. However, the high evaporation rate of water cannot be preserved due to the inevitable fouling of solar absorbers. Herein, a self-floatable and super hydrophilic solar-driven steam generator composed of activated carbon coated melamine foam (ACM). The deposited ACM photothermal layer exhibits outstanding solar absorption (92%) and an efficient evaporation rate of 1.27 kg m−2 h−1, along with excellent photothermal conversion efficiency (80%) as compared to commercially available primitive solar stills. The open porous assembly of melamine foam equipped with 80% flexibility (0.8 MPa) enabled smooth water transport and sustain heat accumulation within the matrix. The thermal insulation of ACM is 10 times greater than pure water. Moreover, open porous assembly of designed solar-powered steam generator rejects salt ions as well as volatile organic compounds efficiently. The low-cost and facile fabrication of photothermal based water production presents a potential solution to single step drinking water supply from various resources of the sea, the lakes and mixtures of emulsified oil and industrial wastewater.
