Title (EN) REGENERATION PROCESS OF A FILTERING APPARATUS AND DEVICE FOR IMPLEMENTING SUCH PROCESS
(FR) PROCEDE DE REGENERATION D"APPAREIL DE FILTRATION ET DISPOSITIF DE MISE EN OEUVRE
Abstract:
(EN) Fully automatic process for regenerating filters in general, but more specifically intended for filtering liquids, and filter for carrying out such process. The regeneration process takes place according to a precisely sequenced cycle at the end of which a concentrated solution of sediments is collected allowing a direct elimination of the latter. The filter allowing to carry out such a process is provided with appropriate means (6) ensuring an efficient unclogging of the filtering elements (16). Application to the filtration of a circuit with circulating fluids which can be contaminated such as for example the secondary circuit of a nuclear reactor.
(FR) Procede entierement automatique de regeneration de filtre en general, mais plus specialement destine a la filtration de liquides et un filtre permettant la realisation de ce procede. Le processus de regeneration se deroulant selon un cycle bien precis a la fin duquel on recupere une solution concentree de sediments permettant une elimination directe de ceux-ci. Le filtre permettant la realisation d"un tel procede est equipe de moyens (6) appropries assurant un decolmatage efficace des elements filtrants (16). Application a la filtration de circuit vehiculant des fluides pouvant etre contamines tel par exemple que le circuit secondaire d"un re.
