, Enfin, l'application de la membrane TW30 pour la production d'eau potable à partir d'un forage contenant 413,74 µg/L d'arsenic total dont 405,63 µg/L d'arséniate

, Il est donc possible de mettre en place un procédé de traitement de ces eaux de forage à partir de la membrane TW30

, Ce système permet de produire un volume d'eau équivalent à 70% du volume d'eau à traiter. Le dépôt des solutés à la surface de la membrane étant lent, la membrane pourra avoir une durée de vie plus longue du fait de nettoyage moins fréquent. Par ailleurs, la recirculation du retentât (c'est-à-dire des 30% d'eau restant) réduire la performance du système
