Description
This powerpoint presentation begins by providing a brief overview of wastewater reuse. Fouling in ultrafiltration (UF)/microfiltration (MF) is presented, along with effluent organic matter (EfOM) – removal and fouling;dealing with EfOM – generic measurements,fractionation schemes, diagnosing problems; coagulation to remove EfOM and reduce fouling; and,applications – from the lab bench to real systems. Presentation conclusions indicate the following: we can improve UF treatment of EfOM (and other wastewatermaterials) by understanding speciation effects and using pretreatment, we’re now looking at MIEX;autopsies for failed membranes may result in incorrectconclusions (HPO/HPI acids cause fouling, HPO/HPIbase/neutrals stay on top of membrane);coagulation works, even with removal of a portion of HPOacids; EfOM and SMP result in similar fouling; and, big changes in fouling due to alginate, AHA, and SRNOM dueto Ca+2. Includes figures.
