Abstract

Abstract: Human Powered Water Purifier is the system which provides safe drinking water by running a RO systemwith the help of only human power and minimal setup.This can prove to be a major cost effective solution tothe problem of unsafe drinking water in areas where there is no or little access to modern purifiers or they do not have the power source to run them ( either irregular electricity supply or in emergency situations). This paper explains in detail about the design of an indigenous mechanism which makes useof human pedalling on a bicycle & power istransmitted by sprocket and belt pulley system toobtain required RPM for pump to run a water purification system. It includes a brief picture of the need of this type of system, design of various components and the summary of results obtained during the testing of the system. This mechanism has shown positive results in maintaining the pressure andflow Rate from pump by providing about 1200 RPM with mechanism, required by RO Purifier and TDS (Total Dissolved Solids) in water was considerably reduced from 650 ppm to 150 ppm.
