Title : Application of electron beam to treatment of wastewater
Electron-beam treatment of wastewater from a papermill has been
studied in combination with conventional methods
(coagulation+flocculation and biological). It has been found that such
combination (the required dose is about 1 kGy) allows one to decrease
chemical oxygen demand and total organic carbon values of wastewater to
the value below 25 ppm and, as a consequence, to increase the
recirculation rate of wastewater from 20–30% up to 70–80%.
The design of commercial plant equipped with three electron
accelerators (total beam power 300 kW) for the purification of
wastewater from a papermill in Cheongwon (Republic of Korea) has been
developed. Its planned output is equal to 15,000m3/day.
