Design and Performance Evaluation of Solar Water Distillation Plant
Pure water is most essential for human life. But it is not available and rare in most of the place in the world. Pure water is not only important for drinking purpose but also for other issue such as boiler make up or feed water, distilled water for medical uses etc. Hence purifying water is the demand of time. Water purifying is an energy consuming process but our conventional energy resource is limited. In that case alternative renewable energy resources can give us better solution. Solar energy is available resource and gives an optimum solution for this experimental purpose. Designed solar water distillation plant has two parts. Upper part is made by glass and a copper plate for absorbing heat inside it. Proper Insulator is attached behind this arrangement. A small container is linked below it by a small elbow, condensed pure water stored in this container. The lower part is made by cellulite. The cellulite box contain wick. This wick spread from the ground to the backside of copper plate. The wick absorbs the ground water and conveys it up to glass box where this water is evaporated in presence of solar energy. Total system is completely air tight. This plant works quit well but its performance is most depended on wick material. A composite wick material can gives better result.
