Textile dyeing processes are characterized as high consumption of water, steam and electricity, and discharge of the filthy and colored wastewater. Increased use of assorted dyes and other chemicals hurries in re-equipment of purification facilities by application of efficient methods based on radiation technology. Based on the pilot plant operation since 1997 at Daegu Dyeing Industrial Complex (DDIC), a commercial plant has constructed in 2005. Electron accelerator of 1MeV, 400kW with three separate irradiators was used for the flow rate of 10,000m3 per day. Wastewaters are delivered through the injection nozzles under the electron beam. Continuous operation of this plant showed the preliminary electron beam treatment reduced bio-treatment time twice at the same degree of removal and resulted in more significant decreasing TOC, CODCr, and BOD5. This project is supported by the International Atomic Energy Agency (IAEA), Korean Government and the City of Daegu.
