The Korea Atomic Energy Research Institute (KERI) has been developing new technologies that can fundamentally remove industrial odors using low-energy electronic wires and is commercializing them.

The Korea Atomic Energy Research Institute announced on the 15th that Dr. Kim Byung-nams team of the radiation use operation department has developed a low energy electronic accelerator-based odor removal fusion system with Eco Core Technology Co. Ltd. a company specializing in odors.

The newly developed system uses technology to break down molecular bonds of odor-causing substances by accelerated electrons in electronic accelerators.

Air containing odors is passed through the intake of the low-energy electron accelerator in which the electron breaks down the molecular structure of the odor-causing substance and releases air to the outlet.

In other words the odor materials that are pinched by the electron beam in the accelerator break the molecular structure as the chemical bond is cut which also eliminates the odor at its source.

The Korea Atomic Energy Research Institute has developed this technology since 2016 and confirmed the performance of 99% of its odor removal efficiency after conducting an empirical test in November.

Despite many advantages such as relatively low construction costs the odor removal technology using low-energy electronic accelerators has been difficult to apply to large-capacity odor treatment due to the low penetration depth of the electron beam.

However Dr. Kim Byung-nams team overcame the low penetration depth problem and dramatically expanded the area by introducing a spiral structure inside the reactor so that the electron beam can be evenly examined in the air passing through the reactor.

As a result they achieved a throughput capacity of 22CMM [Cubic Meter/Min] 99% of treatment efficiency with no distinction between low and high concentration of odors (10000 to 40000 OU [Odor Unit) generated at the site.

By adjusting the size of the reactor the capacity can be increased by up to 300 to 400CMM which is sufficient to remove large-scale odors.

The institute has registered 3 out of 5 domestic patent applications related to this technology and has applied for 1 PCT (International Patent Treaty) and is waiting to be selected as an overseas entry country.

This technology can be applied not only to the stench of industrial sites but also to serious stench-causing facilities such as land sewage sludge treatment plants and excrement odor.

In particular the application of the air conditioning system in large hospitals is expected to have an excellent effect on preventing infection in hospitals through indoor air.

Dr. Kim Byung-nam who led the research said We will speed up commercial model development and new technology certification to apply this technology to industrial sites as soon as possible.
