WADI: The New Portable Clean Water Method
Throughout the world, there have been several innovations to generate new portable clean water in developing nations. The latest of these innovations is WADI, a water purification system started by the Australian corporation Helioz.
According to Helioz’ research team, WADI is an easy to use, cost effective UV measurement device for solar water disinfection (SODIS). In short, WADI is a solar powered water disinfection system that operates “without the use of chemicals, batteries or filters”. Because of its pure use, WADI guarantees its users with safe, chemical-free drinking water.
The WADI device is simple and easy to use. A user simply fills in a PET bottle with water from any source, puts the WADI device on instead of the regular bottle cap, and exposes the bottle to sunlight and UV rays until the water in the bottle registers as clean on the device. If the water is still contaminated, the device will show a sad face to the user.
If the water has been purified, the device will register a smiley face on it’s small LCD screen. However, the device does face some challenges. Although the device shows serious advancement towards clean water around the world, it also has setbacks in areas where water sources and sunlight are scarce.
In areas where sunlight is scarce, the cleaning process might take up anywhere from 45 minutes to two days longer than normal. As a result people who are in desperate need for water resort to drinking contaminated, more accessible water, researchers say.
However, the self sufficient water purification system promises to take the world by storm. The project is expected to launch in developing nations in January 2014. Currently, Helioz is working on a funding campaign for the device.
The campaign will allow the company to create a further study on the effects the device has on remote villages such as Odisha, India. The study will also help the company customize their product depending on the area it is being used in.
Projects such as WADI show great promise towards completing worldwide water purification. However, only time, and user responses will tell if the project is a success.
