[Asia Economy (Suwon) = Reporter Lee Young-gyu] Gyeonggi Province has filed a patent for an eco-friendly technology that can reduce operating costs by 50% for removing harmful chemical substances.
The Gyeonggi Provincial Institute of Health and Environment announced on the 30th that it filed a patent on the 18th for a new environmental technology that can be easily applied to remove trace amounts of harmful chemical substances such as color in wastewater and sewage, as well as for water purification, reducing operating costs by about half compared to existing methods.
The patented technology, called the "Water Quality Purification System Using Raw Water Division and Chlorine-based Oxidative Coagulation under Acidic Conditions," focuses on chemically altering the characteristics of trace harmful chemical substances such as color, which exist in chemically stable structures in wastewater and sewage.
The Institute explained that this new technology is more than 50% cheaper in treatment costs compared to commonly used methods such as ozone oxidation, Fenton oxidation, and activated carbon adsorption for removing trace harmful chemical substances like color. It also added that it can be effectively applied to water purification when raw water quality deteriorates due to increased turbidity from rainfall or algal blooms.
The Institute plans to apply this technology to the "Hantan River Basin Sincheon Color Removal Improvement Project," which is currently underway.
Park Yong-bae, director of the Gyeonggi Provincial Institute of Health and Environment, stated, "We plan to apply the developed eco-friendly new technology to the Hantan River color improvement project and transfer the technology to domestic water companies. We will also distribute it to new water markets where sewage treatment coverage is rapidly increasing, including Southeast Asia and Latin America, as well as domestically."
