AWWA ACE65395

The objective of this powerpoint presentation was to examine the impact of membranepretreatment strategies on membraneperformance evaluated in terms of total organic carbon (TOC) removaland membrane fouling. Two strategies are explored, including: dual coagulation with an inorganic salt anda prehydrolized coagulant; and,intermittent coagulation. The experimental set-up included: ZW1000 jr modules (1 m²);outside-in configuration;pore size ~ 0.04 & #181;m; and,Hamilton Bay water(Ontario, Canada). Topics outlined under the first strategy of dual coagulation include: TOC removal alum/PACl (summer); TOC removal alum/PACl (winter); fouling rate alum/PACl (winter); TOC removal ferric/PACl (summer); fouling rate ferric/PACl (Summer); TOC removal ferric/PACl (winter); and, fouling rate ferric/PACl (Winter). Topics outlined under the second strategy of intermittentcoagulation include: TOC removal; and, fouling rate. Includes table, figures.
