Abstract: front page image
(EN)Process and device for so-called biofilters, in which polluted gas, e.g. air, is made to pass through, and thereby be cleaned in a bed of bed media arranged in a container, comprising measuring of the moisture content of the bed and the supply of fluid, e.g. water, in order to maintain the desired moisture content, wherein the moisture content of said bed (3) is measured by means (9; 23, 23') which are not in contact with the bed media.
(FR)Procédé et dispositif destinés aux filtres dits biofiltres. Selon le procédé, on fait passer du gaz pollué, air par exemple, de façon à le purifier, dans un lit contenant un milieu disposé dans un récipient. On mesure la teneur en eau du lit et l'alimentation de ce dernier en fluide, eau par exemple, afin de maintenir le degré d'humidité désiré. La teneur en eau dudit lit (3) est mesurée par un système (9, 23, 23') qui n'est pas en contact avec le support.
