This project demonstrates the value of nanofiltration to meet multiple treatment objectives including disinfection byproducts (DBP) control and atrazine removal. A rigorous membrane selection process driven by the atrazine rejection criteria lead to the selection of superior membrane in terms of permeate water quality and operating pressures. This project illustrates how utilities can maximize the resources committed to meeting the ICR requirements and develop information specific to their facilities for long term planning purposes. Includes 12 references, tables, figures.
