Title : Application of an Electron Accelerator for the Treatment of Wastewater from Textile Dyeing Industries

ABSTRACT

Textile dyeing processes consume a great amount of water and steam and discharge filthy and colored wastewater. Increased use of assorted dyes and other chemicals has increased the pace of reequipping purification facilities by applying efficient methods based on radiation technology. Based on laboratory data, a pilot-scale e-beam plant was constructed at the Daegu Dyeing Industrial Complex (DDIC) in 1998. An electron accelerator, 40 kW at 1 MeV, was used for 1,000 m3 per day. Continuous operation of this plant showed that the preliminary e-beam treatment reduced the bio-treatment time and resulted in significant decreases in the TOC (total organic carbon), CODCr (Chemical Oxygen Demand as dichromate method), and BOD5 (Biochemical Oxygen Demand in 5 days). Convinced of the economics and efficiency of the process, a commercial plant with a 400-kW electron accelerator was constructed in 2005. This plant improved the removal efficiency of
wastewater by decreasing the retention time in a bio-treatment facility with a dose of approximately 1 kGy. This plant is located in the vicinity of an existing wastewater treatment facility in the DDIC, and the treatment capacity is 10,000 m3 of wastewater per day.
