AWWA ACE63054

This slide presentation outlines a study on bromide removal using MIEX® resin and ceramic membrane filtration. Background information is outlined and includes: Nationwide disinfection byproduct (DBP) Occurrence Study; Brominated DBPs; and, Tailored Collaboration Study (AwwaRF and Palmdale Water Department, California). Materials and methods are outlined and include: MIEX® Ion Exchange Coupled with Low-Pressure Ceramic Membrane Filtration; MIEX® Resin and Ceramic Membrane Characteristics; and, Experimental Matrix. Results include and outline of Finished Water Quality, Percent Removal of Bromide and Dissolved Organic Carbon (DOC), and Hydraulic Performance. Conclusions indicate that: total trihalomethane (TTHM) water quality goals can be achieved, with good success at meeting 80 µg/L regulatory limit (13/16 conditions) and moderate success at meeting 60 µg/L project goal (7/16 conditions); short-term membrane fouling dependant upon recirculation loop resin concentration, flux, and crossflow velocities; and, exchange kinetics sufficiently rapid for removal of bromide and TOC, under conditions tested. Includes tables, figures.
