The results of studies evaluating the efficiency of fog dispersion by collecting water droplets contained in the fog using the grid electrostatic precipitator are considered. The precipitator includes a corona discharge generation system that provides electric charging of fog droplets and a grounded gauze structure free for airflow. When air flows through the cells of the grounded conductive gauze, electrically charged drops are deposited on its surfaces and are separated from the wind stream. The airflow purified from drops is directed to the protected area and forces fog out of it. Data of the presented studies are based on the experiments conducted in the large aerosol chamber of the Institute of Experimental Meteorology (Taifun Research and Production Association). High efficiency of the investigated method is shown, it may be recommended for practical work to improve visibility in fog in a controlled area.
