An installation for decontamination of ballast water and other water media in stream contains vacuum-forming device, inlet and outlet pipelines. The vacuum-forming device is made in a form of nozzle, mounted in front wall of a vacuum chamber, equipped with combined pressure gage. The inlet pipeline is equipped with connected in series filter, pump, flowmeter, thermometer and manometer, and the outlet pipeline is equipped with back-pressure valve and manometer, besides the length of vacuum section in reference to diameter of its cavity is equal to L = (315)D, where L – the length of vacuum section, D - diameter of cavity of vacuum section, and the nozzle length in reference to diameter of its initial cut is determined in ratio of l/d= (0,77), where l- the length of nozzle, d– diameter of nozzle, and the ratio of sectional area of nozzle at the level of edge and sectional area of vacuum-chamber makes up, where f – nozzle area, F – area of vacuum chamber. |
