Portable heat exchanger to purify water

Abstract

The project aims at harvesting residual heat from Internal Combustion engines to purify water. This effort is intended to develop a user-friendly portable water purification system. By developing this product, users will be able to optimize self-reliance in fulfilling their requirement of drinking water. Therefore, the initiative will have environmental value by reducing dependence on commercially available bottled water. It becomes more important for the underdeveloped countries where tap water is not portable and reliance on bottled water is very heavy. Cars are on the most frequently used modes of transport for urban populace. If we are able to provide a mechanism through which water can be purified using the exhaust heat of car engine and promote this solution, everyday large amount of water will be purified while users are performing their regular activity of driving. The product will basically take impure locally available water, soften it, and kill the harmful bacteria causing water-borne diseases. This product can be asset for the lorry/truck drivers who travel over long distances and can't rely on the quality of water available in developing countries like India. Thus it will be important to keep the product as cheap as possible. © 2016 IEEE.
