Title (EN) IMPROVED FILTER CLEANING METHOD
(FR) PROCEDE AMELIORE DE NETTOYAGE D'UN FILTRE
Abstract: front page image
(EN)A method of cleaning a filter clogged with flocculating materials is provided. The method comprises determining the flocculated materials clogged on the filter and adding a dispersing agent to break up said flocculated materials to form dispersed precipitates. Then the dispersed precipitates are removed from the filter in a regular cleaning such as backflushing.
(FR)L'invention concerne un procédé de nettoyage d'un filtre obstrué par des produits floculants, consistant à déterminer les produits floculés déposés sur le filtre et obstruant celui-ci, et à ajouter un agent dispersant pour fragmenter lesdits produits floculés de manière à former des précipités dispersés. Les précipités dispersés sont ensuite retirés du filtre lors d'un lavage régulier, par exemple à contre-balayage.
