" Pedal Powered Water Purification By Reverse Osmosis" The Earth is covered in over 75% water, yet one of the world’s greatest issues is a lack drinking water. “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 world. 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. Clearly, access to potable water around the world is an exceedingly urgent issue in which action should be taken immediately. In response to such a need, this idea is proposed to produce clean drinking water by reverse osmosis filtration by means of human power. There are several means to purify water; however, because of its incredible thoroughness, a reverse osmosis system has been preferentially selected for this design

2. 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’.

3. Reverse Osmosis
Two liquids of different concentrations separated by semi-permeable membrane.
Less saturated solvent naturally flows into more saturated region.
Pressure is applied to reverse this
process and is known as reverse
osmosis or RO.
 Dirty water flows through
membrane thereby filtering it.
dirty water  clean water

4. 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 etc
The purpose of this project is to design and fabricate a small scale water
purification kit which requires minimal maintenance and which is cost
efficient.

6. METHODOLOGY
In 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.

7. METHODOLOGY
Then 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 Membrane
Here water is converted into pure water by reverse osmosis process, where
impure water is separated and pure water is collected in container.

8. FUTURE SCOPE
• In 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.

9. 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.
