The Environmental New Technology system is designed to promote the practical application of outstanding technologies in the environmental sector by having the state certify and verify them, thereby strengthening the competitiveness of the environmental industry. It is divided into "New Technology Certification" and "Technology Verification."
The New Technology Certification is granted after a comprehensive evaluation of the technology's novelty, excellence, on-site performance, and applicability. Technology Verification is a process to confirm whether the certified technology demonstrates the expected performance in actual environmental sites. In particular, in the field of wastewater treatment, both certifications must be obtained to receive benefits such as additional technical points in public tenders.
The environmental new technology for which CJ Logistics Construction Division has simultaneously obtained certification and verification is the "High-Efficiency Wastewater Membrane Separation Treatment Technology (CHAMP) using automatic influent water division injection based on the Carbon/Nitrogen ratio (C/N ratio) and a hybrid jet-venturi mixer."
This technology is suitable for small- and medium-sized sewage treatment plants with significant fluctuations in water quality depending on the time of day, as well as factory-type wastewater treatment facilities with complex wastewater from various processes. If nitrogen and phosphorus are not properly treated and flow into rivers, it can cause eutrophication, leading to environmental problems such as algal blooms and foul odors.
This technological achievement was accomplished about four years after development began in January 2021 at the Opo Clear Water Restoration Center in Gwangju, Gyeonggi Province.
Min Younghak, CEO of CJ Logistics Construction Division, stated, "This Environmental New Technology Certification is the result of our ongoing research into water treatment technology, based on the membrane bioreactor (MBR) technology that we have been developing in-house since the late 1990s," adding, "We will continue to devote our efforts to developing even more advanced water treatment technologies and contribute to the creation of a healthy aquatic ecosystem."
