Pedal Powered Water Filter

Pedal Powered Water Filter
Pure water is precious and its value is known to those people who do not get it. According to the WHO, such disease-account for an estimated 4.1% of the total DALY(Disability-adjusted life year) global burden of disease, and cause about 1.8 million human deaths annually. Waterborne diseases are caused by pathogenic microorganisms that most commonly are transmitted in contaminated freshwater. In my last post, I discussed how we can purify it with solar energy. Though in summer solar water purifier is a good option in winter or rainy season it becomes very inefficient and slow.

We need a system which can work the whole year whether it is day or night. A pedal Powered water filter is one such solution. It is a green and pollution-free method of purifying water using human labor.

How it works?

We all know how nature filters our water. It evaporates dirty or seawater and later condenses it in the form of rain which is pure drinking water. Pedal-powered water purifier works on the same concept. In this project, we pedal our bicycle to transform water into vapor and later condense it to get clean water.


This project consists of two chambers, copper tube and pipe, one chamber is for dirty water called tank and the second one is a tiny boiler. Both of these chambers are connected using a pipe. When we fill our tank with dirty water, as the pressure of dirty water increases, water starts to transfer from tank to boiler using pipe connected to both of them. In the boiler, water gets heated up to the boiling point using a pedal-powered generator. Water Vapor generated in this process passes through a tank of dirty water using a copper tube and later to the outlet. The advantage of passing water through the dirty water chamber is that it preheats the dirty water and condenses itself to provide us clean water. Video shown below has a complete explanation.

How much price of this project

CG said...

It would not cost much because you can find parts of this project in scrap for eg. copper tube can be found from old AC , you can make chambers from any old plastic material and use dynamo for generating electric current.
