Abstract
A solar still constructed using polymethyl methacrylate (PMMA) represents an improved approach to solar desalination, in which conventional materials such as metal or concrete are substituted or reinforced with PMMA- based composites PMMA sheets are often used as the transparent glazing cover of the solar still instead of glass. It allows maximum solar radiation to pass into the basin, heating the saline/brackish water effectively. A tubular solar still made from polymethyl methacrylate (PMMA) composite is a lightweight desalination system that offers a larger condensation surface compared to conventional designs. The single-slope solar still, a basic yet effective water purification device, utilizes solar radiation to evaporate saline or impure water, and subsequently condenses the vapor to obtain fresh, distilled waterIt consists of a shallow basin filled with saline or contaminated water, covered by a transparent sloping Acrylic Polymethyl Methacrylate (PMMA). The system operates on the principle of evaporation and condensation, mimicking the natural water cycle. The experimental reading was conducted in central India (23.24° N and 77.39° E) in the month of June 2024, from 10 a.m. to 5 p.m. The results indicated that the standard single slope solar still achieved an exergy efficiency of 7.4% and an exergy output of 18 W at peak temperature at 10 am at 39.8 0C temperature.
Keywords: Single slope, solar still, yield, water, exergy.
