Nanofiltration membranes are known to remove a large percentage of naturally occuring organics. Removal are often higher than 90 percent. This is also true for disinfection byproduct (DBP) precursors. Due to the properties, the Information Collection Rule may require water utilities of a certain size and carbon treatment. It is the objective of this paper to describe the organic and inorganic constituents that are rejected by a nanofiltration membrane, to determine the corrosivity of nanofiltration permeate water by conducting pipe loop experiments, and to evaluate method for mitigating corrosion problems.
