Abstract
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.
