This powerpoint presentation begins by providing a brief overview of biofouling in a membrane bioreactor (MBR) system, the fouling potential of extracellular polymeric substances (EPS), and QCM-D technology. Study objectives were to: determine the effects of water chemistry (ionic strength, calcium, and pH) on adherence properties of EPS extracted from different locations in HG-MBR system; and, compare adherence properties of EPS extracted from different locations in the HG-MBR and analyze if there is a correlation with EPS components. Study methodology included: hybrid growth membrane bioreactor (HG-MBR) system; EPS extraction and analysis; and, adherence and physico-chemical characterization of the EPS with QCM-D. Presentation conclusions indicate that: electrostatic repulsion plays a major role in EPS adsorption in which more rigid conformation is formed at higher ionic strength; calcium is specifically interacting with EPS functional groups increasing EPS adsorption and rigidity; increasing the pH, EPS becomes more "fluffy", followed by some desorption; and, no correlation was found between the location of the EPS in the reactor and its adherence properties.
