The abstract discusses the relationship between upstream ozone dose and reverse osmosis (RO) permeate total organic carbon (TOC) concentration at the Pure Water Monterey Advanced Water Purification Demonstration Facility. Ozone is one technology available to reduce lowpressure membrane filtration (MF) fouling; however, it also increases RO permeate TOC, which is regulated in California groundwater replenishment reuse projects. This study is the first of its kind. The paper will include data from online TOC meters, characterization of the RO permeate TOC, including aldehydes, alcohols, and organic acids, and the impact of ozone on reducing MF fouling prevention, oxidizing constituents of emerging concern, and inactivating pathogens.
