Abstract

Des moyens de retenue de contaminants (10, 25) comportent au moins deux arbres rotatifs (11, 12) disposés côte à côte et espacés l'un de l'autre, et un corps poreux annulaire sans fin (18) enroulé autour des arbres rotatifs (11, 12) en vue de tourner dans un sens donné. Un moyen d'acheminement (2) est prévu pour acheminer un matériau non traité sur les corps poreux (18) des moyens de retenue de contaminants (10, 25). Des moyens d'élimination de contaminants (30, 35) sont prévus, chacun possédant un orifice d'aspiration (31) situé en regard des surfaces des corps poreux (18). Tandis que le matériau non traité acheminé sur les corps poreux (18) par le moyen d'acheminement (2) glisse sur ces derniers, un contaminant est retenu par les corps poreux (18), puis éliminé par les moyens d'élimination de contaminants (30, 35).
