Liangjie Dong, a molecular biosciences and bioengineering (MBBE) doctoral student at the University of Hawaiʻi at Mānoa, has developed technology which has initial results that indicate that it removed 99.9 percent of arsenic from drinking water. Dong‘s technology, called MicroNose™, is more cost efficient and more effective in filtration than other filters available for purchase today.
The MicroNose™ features a simple mixture consisting of clay, iron and other common ingredients that, when properly combined and treated, produce absorbent and permeable pottery granules which function similar to the mucous membrane in the human nose.
A conventional filtration process for arsenic removal from water requires a five-step method that is time-consuming and costly. In comparison, MicroNose™ requires only a one-step method that is based on physical absorption, contains no chemicals. Arsenic, a highly poisonous metallic element that is found in rocks, soils and waters, affects more than 100 million people worldwide, according to the World Health Organization (WHO).
Dong and his team members are competing for a $1 million award for the National Academy of Engineering‘s Grainger Challenge to develop a sustainable arsenic filtration solution for Bangledesh.
