Abstract

L'invention concerne un dispositif et un procédé permettant l'inhibition du développement de microorganismes, tels des bactéries, dans un milieu, et en particulier un milieu liquide. Plus précisément, le procédé comprend l'application d'une tension de polarisation au milieu liquide, la fréquence de ladite tension variant, dans un intervalle temporel inférieur à 1 heure, entre une fréquence minimale et une fréquence maximale, la fréquence maximale étant au moins deux fois supérieure à la fréquence minimale.The invention relates to a device and a method for inhibiting the development of microorganisms, such as bacteria, in a medium, and in particular a liquid medium. More specifically, the method comprises applying a bias voltage to the liquid medium, the frequency of said voltage varying, in a time interval of less than 1 hour, between a minimum frequency and a maximum frequency, the maximum frequency being at least twice the minimum frequency.
