Scientists create mind-blowing device to improve water treatment

Scientists at the Korea Institute of Science and Technology have developed an electrochemical technology that can treat wastewater directly onsite as opposed to sending the used water to a large-scale water treatment plant.

This development can drastically improve decentralized wastewater systems that are common in smaller, rural areas far from large water treatment sites. 

Conventional methods of treating wastewater at large plants involve dealing with it in bulk. They employ physical, chemical, and biological processes (bacteria) to filter and digest organic compounds in the water. 

According to the Food and Agriculture Organization of the United Nations, standard-rate digesters in large treatment plants can take upward of 60 days to operate. Even high-rate digesters take at least 10 days. 

This new technology, developed by KIST researchers — Sang Hoon Kim of the Extreme Materials Research Center, Jong Min Kim of the Materials Architecturing Research Center, and Sang Soo Han of the Computational Science Research Center — can effectively reduce the total amount of organic compounds in wastewater in a shorter amount of time. 

Their findings, published in the Applied Catalysis B: Environment and Energy journal, showed the effectiveness of the technology.
