There is provided a system and method for collecting water droplets from an airflow of a cooling tower (8) through condensation of water vapour using an electrostatic separator (20), wherein the electrostatic separator is a single unit electrostatic separator (20) or a multi-unit electrostatic separator. The method for water particles collection from the exhaust airflow of a cooling tower primarily comprises condensing water vapour into large water droplets. It is experimentally proved that electrostatic separation solves the problem of visible plume pollution, and blow down decreased since collected water flows back to the circulating water. Additionally, electrostatic separation results in small pressure drop of the cooling tower (8).
