Introduction :

One billion people do not have access to clean drinking water.95% of water-related deaths occur in the developing world.A person can only live for a few days without water.Our Project is designed to provide clean drinking water in remote regions and emergency conditions like flood, famine, earthquakes, and tsunami.It is based on the concept of reverse osmosis.Reverse osmosis is carried out manually by using Pedal Power.


Reverse OsmosisTwo liquids of different concentrations separated by semi-permeable membrane.Less saturated solvent naturally flows into more saturated region.Pressure is applied to reverse thisprocess and is known as reverseosmosis or RO.Dirty water flows through membrane thereby filtering it.dirty water clean water


Objective:Pedal powered water purification by RO method meets the needs of people without requiring any electrical energy.This filtration system could be brought into remote areas and emergency conditions like flood, famine earthquakes etcThe purpose of this project is to design and fabricate a small scale water purification kit which requires minimal maintenance and which is cost efficient.



RO Filters


Connecting Pipe

METHODOLOGYIn operation by pedalling the cycle man power is converted into mechanical energy which is further converted into hydraulic energy in pump.Rotor of the pump is attached to rear wheel of bicycle which runs due to friction.Pump pumps the water to sediment filter with pressure where dissolved inorganic solids (such as salts) are removed from water.


METHODOLOGYThen water is pumped to carbon filter which removes organic matters, chemicals, contaminants and chlorides using chemical absorption.After carbon filter water is passes through the RO MembraneHere water is converted into pure water by reverse osmosis process, where impure water is separated and pure water is collected in container. 7

FUTURE SCOPEIn disaster prone areas of flood, famine, earthquakes etc.In villages where there are no pure water and electric facilities.It can also be used for house hold applications.Filtering local sources of water would eliminate the need to import large quantities from elsewhere, saving relief funds for alternate uses.


Conclusion:Simple in design and portable.Economical and less maintenance.Effective means for providing potable water.It is viable. Bicycle also acts as an easy way to transport water over far distances.
