Abstract
Society has adapted to increased water stress by expanding drinking water portfolios to include unconventional water sources containing an array of pollutants. For example, potable reuse of municipal wastewater has become increasingly important to meet drinking water demand in arid regions. Full advanced treatment systems employ reverse osmosis (RO) to remove recalcitrant chemicals in conventional wastewater (e.g., home-use pesticides and chelated metals) to produce a clean permeate at ~85% water recovery. However, the remaining ~15% (RO concentrate) contains elevated concentrations of these contaminants that pose a risk to receiving water ecosystems. Meanwhile, halogenated organics are a different set of contaminants that occur in groundwater (e.g., trichloroethylene) and during the disinfection stage of drinking water treatment (e.g., trihalomethanes). These chemicals exhibit diverse structures, complicating their removal. This dissertation therefore investigated two methods to treat evolving waters: 1) Ozone to degrade contaminants of particular concern in RO concentrate, and 2) Electrochemical reduction of halogenated alkanes and alkenes using granular activated carbon (GAC) cathodes.
