Performance Analysis of Solar Based Water Purification System Using Reflector

There is almost no water left on earth that is safe to drink without purification after 20-25 years from today. This is a seemingly bold statement, but it is unfortunately true. Only 1% of Earth's water is in a fresh, liquid state, and nearly all of this is polluted by both diseases and toxic chemicals. For this reason, purification of water supplies is extremely important. Keeping these things in mind, we have devised a model which will convert the dirty/saline water into pure/potable water using the renewable source of energy (i.e. solar energy). The basic modes of the heat transfer involved are radiation, convection and conduction. The results are obtained by evaporation of the dirty/saline water and fetching it out as pure/drinkable water. Water is fundamental to human life on earth for survival and good health. Access to safe water is a major challenge in many communities in developing countries. As word population and social-economy growth societies are challenged to provide fresh water to meet those needs for all of their people. Growing demands of fresh water resource are creating and argent need to developed self-sustained system to meet the demand of fresh water. Among the available purification technologies, renewable energy technologies operate on basic principles of solar water distillation. The sun's energy heat increases the rate of evaporation. As the water evaporates, water vapour rise and condenses on the glass surface for collection. This process removes impurities such as salts and heavy metals as well as eliminates microbiological organisms.
