Abstract

Membrane fouling, increasing the recovery of membrane processes, and treatment and disposal of membrane concentrate are major challenges for water utilities, especially because membrane concentrate can have high concentrations of inorganic salts and dissolved organic carbon (DOC). To increase the recovery of membrane processes, membrane concentrate can be treated and then passed through the membrane for a second time. To achieve this, membrane concentrate is typically treated by precipitation processes to remove the inorganic salts. DOC removal from membrane concentrate is often problematic. Magnetic ion exchange (MIEX) is commonly used for DOC removal in drinking water and therefore can be thought to do the same for membrane concentrate at higher doses. To understand how MIEX performs in high DOC water, preliminary work was conducted to evaluate MIEX treatment of municipal solid waste leachates (DOC > 500 mg/L). In this work, DOC removal by MIEX is explored for membrane concentrate and landfill leachate. 2010
