Abstract: A system and process for enhancing total organic carbon (“TOC”) removal from raw, untreated water while maintaining optimum membrane filter performance.

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.

Abstract: One embodiment of a method to system for enhancing TOC removal while maintaining membrane filter performance is the implementation of a dual pH control system. This embodiment will enhance the ability to maximize TOC removal while maintaining optimum membrane filter performance. By adjusting pH, dosing a chemical coagulant and incorporating liquid-solids separation, a considerably higher degree of TOC removal is possible. By adjusting pH again after liquid-solids separation this embodiment can drastically increase the efficiency of the membrane microfiltration/ultrafiltration system. Thus pH control for soluble organic removal is critical. This pH level however may not be the ideal set point for minimizing membrane fouling which is the basis for this embodiment. An example: the pH set point for optimum soluble organic removal is designated to be 5.5. However, the optimum pH set point for optimum membrane performance is 7.0.
