OPTIMIZATION OF SOLAR STILL FOR POTABLE WATER PRODUCTION USING DOUBLE SLOPE

Distillation under normal conditions occurs by boiling water and collecting the condensed liquid droplets formed. The impurities inside the boiled water can be separated which means that even sea water or river water can be distilled for safe drinking. However, this method is highly costly and is difficult to be produced continuously in remote areas. Another alternative is to use solar stills to produce clean and safe drinking water.
Solar stills are a simple way of obtaining distilled water using radiation from the sun. Some solar still models also enhance the evaporative properties of the stills such as air velocity and water depth to produce a larger amount of yield. The experiments done was purposed to compare the efficiency between glass and plastic stills. The models were double sided stills of glass and plastic cover materials. The efficiency of the model was evaluated by the yield produced and production cost. The results showed that although the glass still model was able to reach higher temperatures of water in the basin, the plastic solar still was still producing even higher production, durable, and more cost effective.
