EFFICIENCY OF THE APPLICATION OF UV + VUV IRRADIATION FOR PREVENTION OF SINGLE-CELL INVASIATIONS CARRIED BY BALLAST WATERS OF SHIPS
Results of an experiment on modeling of decontamination of the ballast water (BW) of vessels contaminated with a unicellular galofilny alga of Dunaliella terricola by irradiation with wave lengths of 254 nanometers and 185 nanometers of the mercury arc lamp of low pressure (LLP) are presented. The experiment models the filling of BW tank by the sea water contaminated with Dunaliella terricola through the unit of decontamination, storage within five days in the BW tank imitating navigation of the vessel, and dumping of the BW through the unit in the port of arrival. Decontamination of contaminated BW is executed according to technology of modern oxidizing processes (Advanced Oxidative Processes, AOP) with participation of ozone and peroxide of hydrogen, acquired in water with a radiation of line of 185 nanometers. It is experimentally established that the suggested method of processing of model ballast water stops reproduction of a test object. The executed research shows prospects of application of UF+VUF irradiation for prevention of transfer by BW of alien single-cell organisms and their invasions into local biocenoses.
