Title : Operation of industrial-scale electron beam wastewater treatment plant
Textile dyeing processes consume large amount of water, steam and
discharge filthy and colored wastewater. A pilot scale e-beam plant with
an electron accelerator of 1 MeV, 40 kW had constructed at Daegu Dyeing
Industrial Complex (DDIC) in 1997 for treating 1,000 m3 per day.
Continuous operation of this plant showed the preliminary e-beam
treatment reduced bio-treatment time and resulted in more significant
decreasing TOC, CODCr, and BOD5. Convinced of the economics and
efficiency of the process, a commercial plant with 1 MeV, 400 kW
electron accelerator has constructed in 2005. This plant improves the
removal efficiency of wastewater with decreasing the retention time in
around 1 kGy. This plant is located on the area of existing wastewater
treatment facility in DDIC and the treatment capacity is 10,000 m3 of
wastewater per day. The total construction cost for this plant was USD 4
M and the operation cost has been obtained was not more than USD 1 M
per year and about USD 0.3 per each m3 of wastewater.
