South Korea’s industrial designers have developed a bag that can be used to transport food. The bag can then be used as a recycling water purifier in underdeveloped areas.
The bag uses ultra-violet (UV) technology to kill most of the microbes and germs, while the bag has an internal filter that can filter out microorganisms larger than 5 nanometers in size. The bacteria that cause tuberculosis are usually around 200 nanometers. Its creator said that the use of solar thermal disinfection (SODIS) technology can ensure that the filter removes all microorganisms, including microorganisms that cause diarrhea, which is the second cause of death of children under the age of five. And before this is malnutrition.
This bag is called a life bag. After being filled with water, the bag is placed in the sun for six hours to ensure that all the microbes are killed. The life bag is equipped with a shoulder strap and can also be used as a backpack. Its capacity is 20 liters.
