Solar Powered Water Purifier

Using the sun to purify drinking water is a great solar project for the do-it-yourself. A solar-powered purification system the size of a microwave oven can yield up to 3 gallons of purified drinking water on a sunny day.


Here’s what you need for a basic solar powered water purifier like the one shown in the figure:


Wooden or sheet metal enclosure Reflective material like aluminum foil

Black paint, used for barbeque pits Sheet of glass

Insulation (the white foam kind is fine) Glue (silicon sealant or similar weather-resistant material)

Black tray that can absorb heat Catch trough and container for purified water

A cross-section of a water purification system.

To assemble your solar-powered water purifier, find a place near a water source (for easy filling) and follow these steps:


Paint the exterior of the wooden or sheet metal enclosure black to enhance absorption.


Install the reflective surface at the back and side walls of the enclosure and glue the insulation to the bottom.


Put a tray of contaminated water inside the enclosure and place the glass on top.


Arrange the catch trough at the bottom of the glass, angled downward to a container (like a plastic jug) to collect the purified water.


Aim the contraption toward the sun.


That’s it — you’re done!

This requirements are readily available and affordable,no much skill is required to build it and therefore it can easily be replicated in other parts of Africa.I have used the system in kitengela-kenya,to provide clean water from dirty water and to remove salts from salty water.basically purifying water.The sun is readily available and places prone to drought and with unsafe water is always known to be sunny..therefore with this project,lets provide clean water4Africa.
