Abstract

Un filtre pour puits comporte une enveloppe cylindrique creuse (1) dont le corps et les extrémités (3, 4) sont constitués d'une pluralité de couches principales de filtration (2) et de couches (10) placées coaxialement les unes sur les autres. Chacune de ces couches (2, 10) se compose d'une tresse polymère (5) saturée avec une résine époxy et posée en spirale par rapport à l'axe longitudinal (6) de l'enveloppe cylindrique creuse (1). Les boucles (7) de la couche principale de filtration (2) sont orientées les unes par rapport aux autres et selon un certain angle par rapport aux boucles (8) de la précédente couche principale de filtration (2) de manière à permettre l'interconnexion des cavités de filtration (9). Les boucles de chaque couche (10) au niveau des parties terminales (3, 4) sont comprimées les unes contre les autres et présentent la même orientation dans chaque couche (10) de manière à former respectivement des fils (11, 12). L'espace compris entre les deux couches principales de filtration (2) est rempli de sable de quartz.
