A Pedal Powered Water Purifier

Abstract

Water is a necessity for every living organism on Earth. However, in certain parts of the world especially in rural areas, clean drinking water is a luxury to the residents. This is because they are not supplied with clean water and thus must source for water from rivers, rainwater, and wells which are often contaminated and unsafe for drinking. The objective of this study is to design and fabricate a functional prototype of a pedal powered water purifier, and to ensure that purified water is safe for consumption based on chemical water analysis. The quality of the purified water will be compared to the Drinking Water Guidelines provided by the World Health Organization (WHO). The system utilizes the distillation method to produce clean drinking water. The charging efficiency of the generator has reached 48.74% at 60rpm cadence. Based on the chemical analysis of purified water, it has been proven that it meets the standards set by WHO and is safe for consumption.
