ELECTRON-BEAM TREATMENT OF HIGHLY-COLORED RIVER WATER

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