Water sources are frequently contaminated with volatile organic compounds from human activities and natural chemical substances. Due to their low boiling points, these compounds volatilize alongside water molecules, thus polluting the water supply [1, 2]. Wastewater treatment methodologies are classified into chemical, biological, and physical processes [3]. Chemical strategies encompass chemical precipitation, coagulation/ flocculation, and advanced oxidation processes, while biological approaches include biodegradation and bioadsorption [4, 5]. Physical methods are delineated into membrane technologies, flotation, and adsorption. These techniques basically operate on two principles: (1) transformation or decomposition of pollutants to attenuate toxicity by altering their chemical structure or properties, and (2) concentration and segregation of pollutants without a change in state, to enhance pollutant removal efficiency. A wastewater treatment apparatus utilizing solar evaporation technology comprises a photothermal layer and an adsorption layer (mass transfer layer) [6]. The photothermal layer absorbs solar energy, converting it into thermal energy, whereas the adsorption layer is tasked with pollutant absorption and vapor transport [7–9]. Some designs incorporate a support layer enabling the adsorbent to remain afloat on the wastewater surface [10]. The objective of this technology is to augment the heat and mass transfer capabilities of the evaporation system by leveraging solar energy, thereby enhancing adsorption effectiveness [11]. The operational principle of this technology is predicated on the thermal and concentration polarization effects, which facilitates an increase in the adsorption rate through elevated temperatures and enhanced evaporation rates, respectively.
