A process has been found which increases the efficiency and effectiveness of the overall filtration system, by reducing the fouling of the microfiltration system, thereby increasing its permeability and reducing the frequency of cleanings necessary. According to one embodiment of the invention, cationic coagulant is used to treat water in the early stages of a water treatment system, and to coagulate and flocculate the contaminants, and thereby resulting in reduced fouling of the microfiltration system, resulting in increase flux, less deposit of colloidal and particulate solids and dissolved organics on the surface of the microfiltration membrane, thereby reducing the frequency and duration of the membrane cleaning and ultimate replacement |
