1. Is it feasible to apply radiation technology for pollution control ?

2. Are there available radiation sources for

pollution control ? 3. What are the limiting factors to apply ?

- Economically Wastewater Treatment

Full-scale application of electron

beam wastewater treatment plant

in Korea (Rep. of) for 10,000 m3/d

of textile dyeing waste water with

1 MeV, 400 kW accelerator.

Capital cost : 3 M$,

Operating cost : 0.33 $/m3

Full-scale application of electron

beam wastewater treatment plant

in China for 1,500 m3/d of textile

dyeing waste water with 1.5 MeV,

100 kW accelerator.

Operating cost : 0.35 $/m3



- Economically Sludge Disinfection

Dewatered sludge, 7,000m3/m (18%SS)

10 kGy 2 ~ 3 $/m3

(dry sludge)


2. Are there available radiation sources for pollution control ?

- Electron Beam : Limited Penetration - Gamma Rays : Low dose rate - Slow productivity

- X-rays : Less efficient in Energy utilization

- Required Power ? + EBFGT 130MW plant (270,000Nm3/h) with 8 kGy : 1.0 MW + W/W treatment of 100,000m3/d with 0.5 kGy : 1.0MW + Sludge disinfection of 30,000 m3/m with 10 kGy : 200 kW

For conventional products (cable, polymer, medical items, food etc.), due to the problems of cooling and material handling speed, it is not necessary for e-beam over 100kW .

Recent Achievement of Electron Accelerator

-. 0.7MeV, 1MW (NHV) for EBFGT (Poland)

-. 1MeV, 400kW (EB TECH, BINP) for W/W (Korea) -. 1MeV, 500kW (NIIEFA) for EBFGT (China) -. 7MeV 200kW, 7MeV 700kW (IBA) for X-ray -. 10MeV 100kW (BINP) for X-ray


3. What are the limiting factors to apply ? - Public Acceptances for Radiation Safety - Technical Reliability for Year-round Operation - Regulations under Regulatory Authorities - Competition with Conventional Technology - Scale-up from Laboratory to Commercial Scale
