A system and process for enhancing total organic carbon ("TOC") removal from raw, untreated water while maintaining optimum membrane filter performance. The present invention overcomes many of the disadvantages of prior art water filtration systems by controlling the pH level of the water, prior to the water being directed through said membrane filter, so that the particulate charge of the water aligns with the electromagnetic surface charge of membrane filter. Maintaining the particulate charge of the water within an optimum charge window for the particular membrane filter enhances the membrane filter's performance by decreasing the fouling rate of the membrane filter.
L'invention porte sur un système et un procédé d'amélioration de l'élimination du carbone organique total (« TOC ») à partir d'eau non traitée, brute, tout en maintenant une performance optimale de membrane filtrante. La présente invention surmonte beaucoup des inconvénients des systèmes de filtration d'eau de l'état de la technique par l'ajustement du niveau du pH de l'eau, avant que l'eau ne soit dirigée à travers ladite membrane filtrante, de telle sorte que la charge particulaire de l'eau s'aligne avec la charge superficielle électromagnétique de la membrane filtrante. Le fait de maintenir la charge particulaire de l'eau dans une fenêtre de charge optimale pour la membrane filtrante particulière permet d'améliorer la performance de la membrane filtrante en diminuant le taux d'encrassement de la membrane filtrante.
