Solarball Efficiently Purifies Water
Published on by Marina A, Previously Key Account and Content Manager at AquaSPE AG in Technology
Solarballs absorb the surface water they float on and use solar energy to evaporate it and purify from contaminants.
Solarball purifies water based on evaporation purification.
It is a clear plastic sphere made of two parts. It allows sunlight to enter it through a transparent layer so that the solar heat can evaporate the dirty water. In the other side of the Solarball, the vapour condenses and the product is clean water.
It can produce 3 to 10 liters of clean water per day.
It is user-friendly and durable.
The problems with solar stills is the need of lenses to concentrate the energy and heat loss.
Solarball evacuates these problems by being made out of a porous, carbon black-coated hydrophilic (water-loving) paper, and expanded polystyrene foam. This enables the water to get inside the ball.
The water is then heated, it evaporates and gets condensed as clean water.
Solar ball is placed to float on a water body so that it absorbs only the surface water, rather than the deeper, colder water. This makes the device significantly more efficient and makes it save heat energy loss.
This way, thermal efficiency of 88% is achieved.
The materials used are all inexpensive and Solarball could be a great solution for communities.
