ELECTRON-BEAM TREATMENT OF HIGHLY-COLOURED RIVER WATER

摘要

The possibility of the application of electron beam for the purification of highly-coloured (40-150 degrees) water was studied. The object of the study was water from the Segezha River (Karelia, Russia) used for the supply of a small town of the same name. It was found that irradiation of this water by electron beam to the dose of 1-3 kGy led to the decrease in its colour to 20 degrees and even less. The required dose depends on the season when the water was taken for irradiation; it is higher for autumn and (partially) spring seasons than for winter and (partially) summer periods. It was also found that irradiation considerably accelerates the sedimentation of suspended particles and ensures the necessary disinfection of the water together with the conservation and even the improvement of its other parameters.
