The device, created by a team at the Korea Institute of Machinery & Materials (KIMM), utilizes a proprietary moisture collection system that operates through a cycle of adsorption, desorption, condensation and sterilization, the institute said Tuesday.
It is twice as energy efficient as conventional dehumidification systems, according to KIMM.
Inspired by natural mechanisms in plants and animals, the technology has been certified for water harvesting performance and drinking water safety by accredited testing agencies.
KIMM has transferred the technology to PureSys, an air pollution solutions company, for commercialization.
"This is a meaningful development that can secure drinking water in areas where water is scarce," said Dr. Lim Hyun-eui, who led the research.
"We will strive to establish a drinking water production system that many people around the world can safely use to address water shortages and droughts."
Researchers designed the system to dehumidify without powering the thermoelectric element during moisture absorption, reducing energy consumption.
They also developed an eco-friendly filter using diatomaceous earth and biodegradable polymers to remove heavy metals and nano-sized microplastics.
The project was supported by the Korea Environmental Industry and Technology Institute under the Ministry of Environment.
