Abstract

This project developed a method to measure assimilable organic carbon (AOC) in salt water to enable more timely evaluations of biofouling potential. This method was developed using a naturally occurring marine bacterium (Vibrio harveyi). The method was refined in the lab using both natural and model waters. This project identified coagulation conditions (coagulant type, dose, and pH) that could be used to improve organic removal in the pretreatment step of two desalination plants.
