ABSTRACT:
The NURTURE water purification project provides a small, economical, water purification system that may be applied on a larger scale. The design has minimal moving parts, thereby reducing the risk of mechanical failure. The final device is driven from a windmill interface. The design easily separates waste and optimizes clean water output. The NURTURE water purification project is intended to fulfill the requirements of the ASME design competition and then be adapted to use a renewable energy source. When adapted to a renewable energy source, this small scale water purification device will attempt to satisfy market needs for individual families who desire purified drinking water. The purpose of this project is to design and manufacture a small scale water purification system which requires minimal maintenance and is cost efficient. Originally, a human powered bike will be used to power the purification system for the competition and a wind turbine will be used to adapt the system to renewable energy. The power produced will be converted into heat by using a resistive heating element which will be placed in a boiling chamber. Once the water is boiled, it is condensed in the heat exchanger and the system will collect the potable water. The final product of the NURTURE water purification system will provide potable water to people around the world.

INTRODUCTION:
It is needless to mention that water, a compound of Hydrogen and Oxygen is a precious natural gift which is very essential for survival of mankind including animals. The water used for potable purposes should be free from undesirable impurities. The water available from untreated sources such as Well, Boreholes and Spring is generally not hygienic and safe for drinking. Thus it is desirable and necessary to purify the water and supply under hygienic conditions for human drinking purpose. As the name implies, the mineral water is the purified water fortified with requisite amounts of minerals such as Barium, Iron, Manganese, etc which can be absorbed by human body. It is either obtained from natural resources like spring and drilled wells or it is fortified artificially by blending and treating with mineral salts. The water filtration project is intended to provide clean drinking water to anyone in need. The lack of clean water supplies could save countless lives every year. A small scale water filtration system could be brought into remote areas and provide the means of purifying previously contaminated water. Filtering local sources of water would eliminate the need to import large quantities from elsewhere, saving relief funds for alternate uses. The purpose of this project is to design and manufacture a small scale water purification system which requires minimal maintenance and is cost efficient.

HISTORY OF THE WATER PURIFIER:
The history of water filters is indelibly tied to the history of water, itself. As human industry has grown and water has become more contaminated, water filters have emerged over the centuries in response to the growing recognition of the need for pure, clean water to drink and the realization that such water does not occur naturally. Water has greatly affected humanity and civilization for millennia. Because water is so absolutely vital to our body systems, we, as living beings, are entirely dependent upon water. In fact, this simple substance, more than any other factor, guided the formation of civilization. Early civilizations were clustered around water sources, and it was water that initiated the first substantial agriculture in the Fertile Crescent, leading to more complex and sedentary civilizations. For centuries, water availability guided the type of foodstuff that could be grown in an area. Water was also the impetus and guiding force behind the first cross-cultural interactions. Early trade was completely dependent upon water, for transportation of goods and sustenance of people and animals.
