Research Paper On Solar Water Pasteurization

Years of research have perfected using solar devices to pasteurize water, and the results have been very successful. Many scientists have developed ways to render the power of the sun to destroy viruses, diseases, parasites, and bacteria found in water, mostly using solar cookers or solar ovens. This newfound procedure for pasteurizing water could be the solution for people in developing countries lacking access to clean, drinkable water. Many lives will be saved if all people have access to clean water, and the spread of waterborne diseases will decrease greatly. The use of solar cookers and ovens just might be the technology that helps achieve this goal.
One of the most respectable scientists in the field of solar water pasteurization, and one of the original founders of Solar Cookers International, Dr. Robert Metcalf has …show more content…
Pasteur created the process of pasteurization to eradicate the microscopic organisms causing disease and sickness using heat. One of the methods for utilizing pasteurization is a solar puddle, which cleans larger amounts of water at a time than solar cookers. Simple models of the cooker are limited to heating small amounts of water at a time. The solar puddle consists of two clear plastic sheets covering a shallow pit in the ground. Solar heat is trapped under the clear plastic sheets, and the water rises to a pasteurization-achieving temperature. The solar puddle has proven to be easy and relatively inexpensive to make. The cost for a family-sized puddle is approximately six US dollars, though prices may vary depending on where the puddles are being made or purchased. Considering the solar puddle is able to heat a larger amount of water at one time than the solar cooker, the puddle may prove to be an alternative method for creating clean and accessible water (Andreatta & Gladstone
