This document describes a pedal-powered water purification system using reverse osmosis. The system uses the pedaling of a bicycle to power a high-pressure pump that pushes water through a sediment filter, carbon filter, and reverse osmosis membrane to remove contaminants. The process produces clean drinking water without using electricity. It is a low-cost solution that is compact and energy efficient, making it suitable for both rural and urban applications.

PEDAL POWERED WATER PURIFICATION
SYSTEM BY REVERSE OSMOSIS
SRI VENKATESWARA COLLEGE OF

Pure water is very much essential to survive but now a days this water is getting contaminated due to Industrialization which leads to many water-related
diseases, our project pedal powered water purification by RO method meets the needs of people without requiring any electrical energy. RO is a pressure-driven
membrane process where a feed stream flows under pressure through a semi permeable membrane, separating two aqueous streams, one rich in salt and other
poor in salt. Water will pass through the membrane, when the applied pressure is higher than the osmotic pressure, while salt is retained. As a result, a low salt
concentration permeate stream is obtained and a concentrated brine remains at the feed side. A typical RO system consists of four major subsystems: pre-
treatment system, high-pressure pump, membrane module, and post treatment system. In operation by pedaling the cycle man power is converted into
mechanical energy which is further converted into hydraulic energy in RO pump. RO pump is attached to rear wheel of bicycle which runs due to friction. RO
pump pumps the water to SEDIMENT FILTER which removes various foreign bodies such as bits of rust, sand silt and dirt .Then the water passes through CARBON
FILTER which removes chlorine and other organic chemicals. The water from pre filters enters into RO membrane, which removes bacteria, pyrogens, pesticides,
asbestos etc .The impurities are flown into drain and the pure water is collected. Simple tests are carried out to check purity of water. This technology has
advantage of a membrane based process where concentration and separation is achieved without a change of state and without use of chemicals or thermal
energy, thus making the process energy efficient and ideally suited for recovery applications.

Design inputs:- ADVANTAGES:- APPLICATIONS:-


 RO Filter Membrane Production cost is low  Perchlorate removal from drinking
It is compact and requires less space water
 Pedal & Water Pump—high pressure
Makes Water purify and also keeps
 GEAR RATIO 2:1 healthy by this exercise  Perchlorate & Nitrate removal from
It can be efficiently used. Ground Water
 Sediment & Carbon Filters

CONCLUSION: -By using Reverse Osmosis we can remove the natural contaminants that are present in water. It is the low cost method to purify the water,
in which we can reduce the pH level near to 7. This is very useful for rural as well as urban people. By cycling, we do our exercise and there by the water
will be purified.
