Abstract
One of the major concerns in rural area is the struggle to get clean drinking water. 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. A structural analysis via Finite Element Analysis (FEA) simulation is performed on the prototype. Then, the quality of the purified water is compared to the Drinking Water Guidelines (DWG) 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. The outcome from FEA results showed that the structure of the supporting frame can withstand up to three times the normal load. In addition, 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.
