"The vision is an efficient washing method that reduces both energy consumption and the need for detergent. This technology can become a global revolution", says Örjan Johansson.
Two proven techniques in a unique combination
Ozone protects us from dangerous UV radiation but also has a cleansing power. The ozone molecule, which consists of three oxygen atoms, is a strong oxidant that is used, among other things, to purify drinking water and decontaminate textiles in healthcare. Ultrasound (high-frequency sound waves) is also used for washing, for example, instruments in healthcare in so-called ultrasonic washers.
"Separately, ozone and ultrasound are proven techniques for efficient cleaning. But the combination is completely new", says Örjan Johansson.
How the washing ball works technically is still a secret, but Örjan Johansson can reveal that the ultrasound will be sent out from the ball's shell via high-frequency vibrations while micrometer-small ozone bubbles are emitted via an ampoule.
The hope is that the new combo will wash our clothes both more efficiently and gently than regular detergents.
"With these technologies, there is the potential to wash extremely clean at the micro level with a minimum of detergent", concludes Örjan Johansson.
