In the current world scenario, electricity and drinking water are the most basic needs in human life. Industrialization and growth within the world's population have enlarged the demand for potable water. Water is obtainable in several forms like ocean water, surface water, underground water and atmospheric water. As freshwater resources are being rapidly ruined and polluted by humans, water shortages pose a great threat to the future. Distillation defines as thermal energy based process that mostly removes impurities from water. In this paper, water desalination experiments using solar energy with various photocatalysts were conducted. Renewable energy driven desalination is becoming more viable despite its expensive infrastructure because it employs free natural energy sources and releases no harmful effects to the environment. Potassium Permanganate (KMnO4), Sodium Acetate (C2H3NaO2) and Potassium Dichromate (K2Cr2O7) were used as photocatalyst materials to improve productivity of solar still. Among used catalysts, the presence of Potassium Permanganate (KMnO4) results in higher yield of fresh water than Sodium Acetate (C2H3NaO2) and Potassium Dichromate (K2Cr2O7). The freezing point of seawater decreases with increasing salt concentration. When solar radiation comes in contact with potassium dichromate, it makes organic materials less soluble. The main goal of this paper is to improve the water quality by building a solar water distillation system with different photocatalyst materials.
