Title (EN) WASTE TREATMENT APPARATUS AND METHODS
(FR) APPAREIL ET PROCEDES DE TRAITEMENT DE DECHETS
Abstract:
(EN) Material to be treated, such as medical waste is placed in a chamber (3) which is then partially evacuated by a vacuum pump (37) via a mixing chamber (35) and a non-return valve (31). One or more pulses of ozone are applied to the chamber (3) from an ozone generator (22) via a non-return valve (26). After each pulse, ozone is drawn from the chamber (3) by the vacuum pump (37) and mixed with steam or water vapour supplied by a source (34). The chamber (3) is then flushed with steam or water vapour from a source (22) and irradiated by a source (13) of ultraviolet, infrared or microwave radiation.
(FR) Des matières à traiter telles que des déchets médicaux sont placées dans une chambre (3) qui est ensuite partiellement vidée au moyen d'une pompe à vide (37) à travers une chambre de mélange (35) et un clapet de non-retour (31). On applique à la chambre (3) une ou plusieurs impulsions depuis un générateur d'ozone (22) à travers le clapet de non-retour (26). Après chaque impulsion, on aspire de l'ozone à partir de la chambre (3) au moyen de la pompe à vide (37) et on le mélange avec de la vapeur d'eau fournie par une source (34). La chambre (3) est ensuite rincée avec de la vapeur d'eau provenant d'une source (22) puis irradiée avec une source (13) de rayonnement ultraviolet, infrarouge ou radiofréquence.
