Assessment of the Effect of using a Magnetic Field on a Single Slope Solar Still Performance Integrated with an External Condenser Unit

As population density rises, the need for potable water grows. Solar distillation is the method of transforming briny water into drinkable water. We use solar desalination to desalinate untreated water. People commonly apply the desalination process to obtain pure water using solar stills. The primary classifications of solar stills are active and passive. This work aims to boost productivity by experimentally implementing the condensation and evaporation processes inside the still. To achieve this, we incorporate a magnetic field and an external condenser into the traditional distillation apparatus. The findings indicate that the outputs of the traditional solar still, the traditional solar still with a magnetic field and an external condenser (CSS-MACO), and the traditional solar still with a magnetic field (CSS-MAG) are 3.800, 5.210, and 5.800 L/m2/day, respectively. Therefore, the utilization of a magnetic field results in a 52.63% increase in productivity, while the combination of a magnetic field and an external condenser leads to a 37.10% improvement, compared to the typical solar still. From a cost analysis perspective, incorporating a magnetic field alongside a conventional solar still is the most cost-effective choice in terms of the total expense per liter of pure water. To be more specific, the cost is 0.016 USD, which is 30.43% lower than the CSS cost.
