ABSTRACT: The aim of this paper is to discover whether human powered reverse osmosis is a viable option for producing potable water for developing countries. The matters at hand are to determine whether human power is enough to operate such a system, how much clean drinking water it will produce, and if it produces a reasonable amount for the work put in. A device was designed to test the practicality of this idea through a numerical analysis. A bicycle inspired design was chosen to harness human power effectively and efficiently. Pedal powered water pumping and purification is not only free from pollution but also provide healthy exercise. Pedal powered water pumping and purification reduces the rising energy costs. Experimental result shows that discharge of about 0.6 l/m can be obtained, and the Total dissolved salt (TDS) is around 50ppm and pH value is around 7.13 for filtered water. Keywords: potable water, filtration, reverse osmosis, human powered, developing countries.…show more content…
“Nearly one billion people do not have access to clean drinking water”. That is about one eighth of all the people living on earth right now. Every year, almost four million people die from water-related diseases and 98% of those occur in the developing countries. Humans can live for weeks without food, but only a few days without water. Many people in developing countries barely have access to any water source at all and for those that do, the water is completely filthy and disease-ridden. Clean water is not only a right of people but also a prime necessity to have healthier lives hence our objective is to design a system which filters water for villages and Remote places by harnessing the human pedal
